dc.description.abstractDepartment of Computer Science, National Chiao Tung University Proposal Title: Application of Machine Learning Approach to Video Coding and Processing Principle Investigator: Wen-Hsiao Peng (PI) Sponsor National Science Council Keywords: Machine Learning, High Efficiency Video Coding (HEVC), Compact Descriptors for Visual Search (CDVS), Encoder control, Visual Search This project aims at applying Machine Learning (ML) approaches to video coding and processing. Recently, production and acquisition of large amount of video/picture data become easier than before. Therefore some problems existing in the model-based video encoding and processing are expected to be solved by data-driven approaches. Since ML is good at dealing with data-driven problems, in this project we shall design highly efficient algorithms for video coding and processing via ML approaches. Our algorithms are based on two international standards being developed by ISO/IEC MPEG and ITU-T VCEG: (1) High Efficiency Video Coding (HEVC) and (2) Compact Descriptors for Visual Search (CDVS). In this 3-year project, we shall accomplish the following works.⑴ In the 1styear the ML approaches are applied to a large amount of data from HEVC compressed videos, trying to solve some difficult classification and parameter estimation problems. Those solutions will lead to the development of fast mode decision, fast rate control and fast parameter estimation, for the HEVC encoder control. (2) For the 2nd year, we study the problem of keypoint selection in the current design of CDVS database construction. ML approaches will be applied to analyze and develop a better keypoint selection algorithm. Moreover, we shall use the ML approach to develop a novel descriptor matching algorithm by merging several well-known matching methods, hoping to achieve higher matching accuracy. (3) Finally in the 3rd year we shall refine our algorithms and enhance them to be hardware-friendly. Furthermore, since HEVC and CDVS standards will be finalized within two years, we shall keep following the standard activities in the first two years.en_US
