| ○ | ○ | Proceedings Paper | Deformable 3D Registration with PWC-Net Optical Flow and Textured Node Correspondences | In this paper, we present an approach for the deformable registration of 3D data via an RGB-D camera to reduce depth distortions in featureless regions. We employ the established PWC-Net based Optical Flow algorithm to identify pixel correspondence between nearby frames and then densely and uniformly select transformation nodes. Color correspondence of the transformation nodes is used in both global and local deformations. Several experimental results show that the proposed method results in low distortion during the non-rigid registration of multiple RGB-D images. | Ding, Jhen-Yi; Lee, Junesuk; Park, Soon-Yong | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Park, Soon-Yong/HGV-2374-2022 | 57215565476; 57210786619; 7501834063 | TWELFTH INTERNATIONAL CONFERENCE ON MACHINE VISION (ICMV 2019) | 0277-786X | 1996-756X | 11433 | 0 | 2025-06-25 | 0 | 0 | Deformable Registration; Node Correspondence; 3D Depth; Non-rigid ICP | 3D Depth; Deformable Registration; Node Correspondence; Non-rigid ICP | Computer vision; Optical flows; Textures; 3D Depth; Color correspondences; Deformable registration; Local deformations; Node Correspondence; Non-rigid; Nonrigid registration; Optical flow algorithm; Deformation | English | 2020 | 2020 | 10.1117/12.2559515 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Proceedings Paper | Depth measurement using engineering point spread function with coded aperture | Depth extraction and recovery from the recorded image have been studied and applied in many fields such as biology, robotics, and computer vision. In some researches, the aperture in the imaging system is coded as a particular function in order to distinguish relative distances from the focal plane or recognize sampled points from the recorded image and the image captured through this coded aperture is useful to retrieve blurred images or acquire depth maps. These studies are associated with the shape of point spread function (PSF). In some approaches, diffraction-based engineered PSFs such as double-helix and cubic phase are applied to extract the depth information. In this paper, we propose a depth measurement method based on the optical analysis of the pupil function. It is well known that the PSF is represented as a Fourier transform of the product of pupil function and spherical phase in a coherent imaging system. Also, it is possible to estimate the intensity of the PSF corresponding to the distance of the object in an incoherent imaging system. Then the depth information is extracted from a snapshot image by inverse transform of the image. | Kim, Beomjun; Heo, Daerak; Jeon, Hosung; Jung, Minwoo; Kim, Hwi; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Korea Univ, Dept Elect & Informat Engn, Sejong 2511, South Korea | 57216150371; 57197871664; 56663784700; 57216159562; 8933596300; 10142501600 | jhahn@knu.ac.kr; | PRACTICAL HOLOGRAPHY XXXIV: DISPLAYS, MATERIALS, AND APPLICATIONS | 0277-786X | 1996-756X | 11306 | 0 | 2025-06-25 | 1 | 0 | Depth map camera; Coded aperture; Image processing | Coded aperture; Depth map camera; Image processing | Holographic displays; Holography; Image processing; Imaging systems; Inverse transforms; Optical data processing; Coded apertures; Coherent imaging systems; Depth information; Depth Map; Incoherent imaging; Measurement methods; Optical analysis; Relative distances; Optical transfer function | English | 2020 | 2020 | 10.1117/12.2545541 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Design and Analysis of an Approximate Adder with Hybrid Error Reduction | This paper presents an energy-efficient approximate adder with a novel hybrid error reduction scheme to significantly improve the computation accuracy at the cost of extremely low additional power and area overheads. The proposed hybrid error reduction scheme utilizes only two input bits and adjusts the approximate outputs to reduce the error distance, which leads to an overall improvement in accuracy. The proposed design, when implemented in 65-nm CMOS technology, has 3, 2, and 2 times greater energy, power, and area efficiencies, respectively, than conventional accurate adders. In terms of the accuracy, the proposed hybrid error reduction scheme allows that the error rate of the proposed adder decreases to 50% whereas those of the lower-part OR adder and optimized lower-part OR constant adder reach 68% and 85%, respectively. Furthermore, the proposed adder has up to 2.24, 2.24, and 1.16 times better performance with respect to the mean error distance, normalized mean error distance (NMED), and mean relative error distance, respectively, than the other approximate adder considered in this paper. Importantly, because of an excellent design tradeoff among delay, power, energy, and accuracy, the proposed adder is found to be the most competitive approximate adder when jointly analyzed in terms of the hardware cost and computation accuracy. Specifically, our proposed adder achieves 51%, 49%, and 47% reductions of the power-, energy-, and error-delay-product-NMED products, respectively, compared to the other considered approximate adders. | Seo, Hyoju; Yang, Yoon Seok; Kim, Yongtae | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Intel Corp, Intel Labs, Santa Clara, CA 95054 USA | ; Seo, Hyoju/GSD-8672-2022; Yang, Yoon/AGQ-1174-2022 | 57215662369; 36162192400; 55699627900 | hyoju@knu.ac.kr;yoonseok.yang@intel.com;yongtae@knu.ac.kr; | ELECTRONICS | 2079-9292 | 9 | 3 | 2.98 | 2025-06-25 | 35 | 53 | approximate adder; approximate computing; hybrid error reduction; low power; energy efficiency | ENERGY-EFFICIENT IMAGE | Approximate adder; Approximate computing; Energy efficiency; Hybrid error reduction; Low power | English | 2020 | 2020-03 | 10.3390/electronics9030471 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Design and Analysis of Metal-Oxide-Semiconductor Field-Effect Transistor-Based Capacitorless One-Transistor Embedded Dynamic Random-Access Memory with Double-Polysilicon Layer Using Grain Boundary for Hole Storage | In this work, a capacitorless one-transistor embedded dynamic random-access memory based on a metal-oxide-semiconductor field-effect transistor with a double-polysilicon layer structure has been proposed and investigated using technology computer-aided design simulation. By using the grain boundary for hole storage, a higher sensing margin of 4.35 mu A/mu m is achieved compared to that without using the grain boundary. Furthermore, the proposed device achieves a superior retention time of 555.77 mu s, which is reasonable from the viewpoint of its application in embedded systems (>100 mu s), even at a high temperature of 358 K. For higher device reliability, the effect of the grain boundary on the capacitorless one-transistor embedded dynamic random-access memory is analyzed with different trap distributions. The proposed capacitorless one-transistor embedded dynamic random-access memory cell exhibited superior reliability in terms of retention time (>100 mu s). | Jang, Won Douk; Yoon, Young Jun; Cho, Min Su; Jung, Jun Hyeok; Lee, Sang Ho; Jang, Jaewon; Bae, Jin-Hyuk; Kang, In Man | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; KIST Korea Inst Sci & Technol, Ctr BioMicroSyst, Brain Sci Inst, 5 Hwarang Ro 14 Gil, Seoul 02792, South Korea | Lee, Sang Ho/MCX-8396-2025 | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 11 | 0 | Capacitorless; Embedded Dynamic Random-Access Memory; Polysilicon; Grain Boundary; Technology Computer-Aided Design Simulation | THIN-FILM TRANSISTORS; POLYCRYSTALLINE-SILICON; TECHNOLOGY | English | 2020 | 2020-11 | 10.1166/jnn.2020.18767 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | Design and implementation of a multi-disaster risk assessment database system in South Korea | To cope with natural disasters and their impact, various types of risk assessment tools have been developed to assess hazards from a scientific point of view as well as the socioeconomic impacts of a hazardous event. Because most of the assessment tools have been developed using local and regional characteristics, there are limitations when applying special cases consisting of various disaster-related datasets in Korea. In this paper, we collected open data scattered among various institutions and guaranteed data interoperability through a standardization process considering various formats. In addition, this study presents a scalable design method and implementation of a database system which can be easily employed in Korean loss estimation due to natural hazards. The proposed database system will be of great help in predicting the disaster scale and degree of damage, in supporting decision-making to minimize damage, and could serve as a data platform of disaster risk reduction and prevention. © 2019 The Author(s). | Chai, Su-Seong; Suh, Dongjun | Korea Institute of Science and Technology Information (KISTI), Daejeon, 245, South Korea; School of Convergence and Fusion System Engineering, Kyungpook National University (KNU), Sangju, 37224, South Korea | 57200090275; 36613529600 | dongjunsuh@knu.ac.kr; | Information (Switzerland) | INFORMATION | N/A | 2078-2489 | 11 | 1 | ESCI | COMPUTER SCIENCE, INFORMATION SYSTEMS | 2020 | N/A | 0.07 | 2025-06-25 | 2 | Database system; Disaster loss assessment; Natural disaster; Open data; Risk reduction | Database systems; Decision making; Design; Disaster prevention; Disasters; Hazards; Open Data; Design and implementations; Disaster risk assessments; Disaster risk reductions; Natural disasters; Regional characteristics; Risk reductions; Socio-economic impacts; Standardization process; Risk assessment | English | Final | 2020 | 10.3390/info11010008 | 바로가기 | 바로가기 | 바로가기 | ||||||||

| ○ | Article | Design of a wideband cymbal transducer array | Cymbal transducers are often used as an array rather than single because they have a high quality factor and low energy conversion efficiency. When used as an array, there occurs a big change in the frequency characteristics of the array due to the interaction between constituent transducers. In this study, we designed the structure of a cymbal transducer array to have ultra-wideband characteristics using this property. First, cymbal transducers with specific center frequencies were designed. Then, a 2x2 planar array was constructed with the designed transducers, where the cymbal transducers were arranged to have same or opposite polarization directions. For this structure, we analyzed the effect of the difference in the center frequency of and the spacing between the constituent transducers on the acoustical characteristics of the array. Based on the analysis, we designed the structure of the cymbal transducer array to have the widest possible bandwidth. | Kim, Donghyun; Roh, Yongrae | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehakro, Daegu 41566, South Korea | yryong@knu.ac.kr; | JOURNAL OF THE ACOUSTICAL SOCIETY OF KOREA | J ACOUST SOC KOREA | 1225-4428 | 2287-3775 | 39 | 3 | ESCI | ACOUSTICS | 2020 | N/A | 3 | Cymbal transducer array; Broadband; Fractional bandwidth; Optimal design | PROJECTOR | Korean | 2020 | 2020 | 10.7776/ask.2020.39.3.170 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Proceedings Paper | Design of SelfEngine: A Lightweight Game Engine | Nowadays, many companies and individuals are developing various game engines on their own purpose. Most of their users and developers may want to update those game engines with new technologies including AI, VR/AR, IOT devices, GPS, blue-tooth devices and many others. To include the new technologies into game engines, they need to know how it works and also where to implement the new feature codes into the engine. Usually large commercial game engines offer plug-ins for the specific technology. However, we don't knowhowlong does it takes to provide that feature, and even though we waited long time, it may be unstable when it first comes up. By developing light-weight game engine with open-source project results, we can integrate varied technologies into the game engine with free cost, and also quickly test new features with ease. To do so, we arranged some design strategies, adopted some open-source projects especially for GUI, sounds, physics, logging systems, model loading, and finally implemented our own core engine system with OpenGL and C++ STL. | Park, Hae Chan; Baek, Nakhoon | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | 57212931500; 7007017954 | oceancru@gmail.com; | INFORMATION SCIENCE AND APPLICATIONS | 1876-1100 | 1876-1119 | 621 | 0 | 2025-06-25 | 0 | 0 | Game engine; Rendering engine; Light-weight | Game engine; Light-weight; Rendering engine | Application programming interfaces (API); C++ (programming language); Technology transfer; Core engines; Design strategies; Feature codes; Game Engine; Light weight; Logging system; Open source projects; Rendering engine; Open systems | English | 2020 | 2020 | 10.1007/978-981-15-1465-4_23 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Detection of collapse buildings using uav and bitemporal satellite imagery | In this study, collapsed building detection using UAV (Unmanned Aerial Vehicle) and PlanetScope satellite images was carried out, suggesting the possibility of utilization of heterogeneous sensors in object detection located on the surface. To this end, the area where about 20 buildings collapsed due to forest fire damage was selected as study site. First of all, the feature information of objects such as ExG (Excess Green), GLCM (Gray-Level Co-Occurrence Matrix), and DSM (Digital Surface Model) were generated using high-resolution UAV images performed object-based segmentation to detect collapsed buildings. The features were then used to detect candidates for collapsed buildings. In this process, a result of the change detection using PlanetScope were used together to improve detection accuracy. More specifically, the changed pixels acquired by the bitemporal PlanetScope images were used as seed pixels to correct the misdetected and overdetected areas in the candidate group of collapsed buildings. The accuracy of the detection results of collapse buildings using only UAV image and the accuracy of collapse building detection result when UAV and PlanetScope images were used together were analyzed through the manually dizitized reference image. As a result, the results using only UAV image had 0.4867 F1-score, and the results using UAV and PlanetScope images together showed that the value improved to 0.8064 F1-score. Moreover, the Kappa coefficiant value was also dramatically improved from 0.3674 to 0.8225. © 2020 Korean Society of Surveying.

| ○ | ○ | Proceedings Paper | Detection of Speech Impairments in Parkinson Disease Using Handcrafted Feature-Based Model on Spanish Speech Corpus | Parkinson disease is a neurodestructive disorder. It gradually dismantles the dopamine chemical producing cells in the brain. The symptoms of the disease arise gradually resulting in infects in movements, olfactory, or speech impairments. The cure for disease is important to prevent patients from major motor and non-motor defects. Computer-aided techniques have been introduced for disease detection and is an open research area. In this paper, we present an approach for early diagnosis of Parkinson disease using the Spanish speech dataset. We modeled handcrafted features from different sets of Spanish recordings and classify them using a machine learning model. Several Machine learning algorithms are implemented for significant classification and compared each other's results graphically. The results depict that handcrafted features of vowels are most efficient in Parkinson disease detection. | Zahid, Laiba; Maqsood, Muazzam; Farooq, Sehar Shahzad; Aadil, Farhan; Mehmood, Irfan; Fiaz, Mustansar; Jung, Soon Ki | COMSATS Univ, Dept Comp Sci, Attock Campus, Attock, Pakistan; Univ Bradford, Fac Engn & Informat, Sch Media Design & Technol, Bradford, W Yorkshire, England; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | Jung, Soon Ki/P-7687-2018; Aadil, Farhan/I-4043-2013; Maqsood, Muazzam/ABE-1733-2021 | 57215563636; 57197810097; 57217701362; 53983838100; 36628922400; 57208735843; 57226791905 | muazzam.maqsood@cuiatk.edu.pk;sehar146@knu.ac.kr;skjung@knu.ac.kr; | FRONTIERS OF COMPUTER VISION | 1865-0929 | 1865-0937 | 1212 | 0.32 | 2025-06-25 | 0 | 1 | Parkinson disease; Speech recognition; Classification techniques; Handcrafted feature; Speech impairments | CLASSIFICATION; DIAGNOSIS | Classification techniques; Handcrafted feature; Parkinson disease; Speech impairments; Speech recognition | Amines; Computer vision; Feature extraction; Learning algorithms; Machine learning; Turing machines; Computer aided technique; Disease detection; Early diagnosis; Feature based modeling; Machine learning models; Parkinson disease; Speech corpora; Diagnosis | English | 2020 | 2020 | 10.1007/978-981-15-4818-5_5 | 바로가기 | 바로가기 | 바로가기 | |||||||||
