Decoding Energy Modeling For Versatile Video Coding
2020 IEEE International Conference on Image Processing (ICIP), 2020 In previous research, it was shown that the software decoding energy demand of High Efficiency Video Coding (HEVC) can be reduced by 15$\%$ by using a decoding-energy-rate-distortion optimization algorithm. To achieve this, the energy demand of the decoder has to be modeled by a bit stream feature-based model with sufficiently high accuracy. Therefore,

An Approximate Versatile Video Coding Fractional Interpolation Hardware [PDF]
2020 IEEE International Conference on Consumer Electronics (ICCE), 2020 In this paper, approximate Versatile Video Coding (VVC) fractional interpolation filters are proposed. They significantly reduce computational complexity of VVC fractional interpolation with a negligible PSNR loss and bit rate increase. In this paper, an approximate VVC fractional interpolation hardware implementing the proposed approximate filters is ...

Performance Evaluation of the Codec Agnostic Approach in MPEG-I Video-Based Point Cloud Compression
IEEE Access, 2021 In this study, we evaluated the codec agnostic approach of video-based point cloud compression (V-PCC) by applying several video codecs to V-PCC. The main concept of V-PCC is to use a video codec to compress the 2D patch images generated from a 3D point ...
