Compared with High-Efficiency Video Coding (HEVC), Versatile Video Coding (VVC) has more flexible division and higher compression efficiency, but it also has higher computational complexity. In order to reduce the coding complexity, a fast algorithm

Lossy compression algorithms are widely used in video coding. However, lossy compressed videos exist some annoying distortion and artifacts, such as blocking, blurring, and ringing. Thus, coding efficiency improvement is a steady-state topic in the d

The latest video coding standard H.265/HEVC is developed to succeed the previous coding standard H.264/AVC. However, a large amount of legacy content was coded with H.246/AVC. Therefore, transcoding from H.264/AVC to H.265/HEVC format is required. Du

The peak signal-to-noise ratio (PSNR) has been widely employed as an objective video quality assessment (VQA) metric. Usually, videos are represented in the YCbCr color space, which results in three PSNR values for each video frame. Several VQA metri

Since modern video coding standards are not designed for processing panoramic videos, the spherical videos are mapped onto a rectangular plane before encoding. Usually the mapping scheme includes two steps: sampling points on the sphere and arranging
