Affine motion estimation (AME) which is newly introduced in versatile video coding (VVC)
plays a significant role in the bit-rate reduction for rotation and zooming scenes. However, it …

The rate-distortion optimization (RDO) framework for video coding achieves a tradeoff
between bit-rate and quality. However, objective distortion metrics such as mean squared …

Digital images have become mainstream of late notably within HDTV, cell phones, personal
cameras, and many medical applications. The processing of digital images and video …

Leveraging massive numbers of sensors in user equipment as well as opportunistic human
mobility, mobile crowd sensing (MCS) has emerged as a powerful paradigm, where …

Fractional motion compensation (FMC) has been widely adopted in modern video coding
standards such as high-efficiency video coding (HEVC). The fractional pixels in FMC are …

Gradients are commonly used in image sharpness assessment methods. However, research
has not fully addressed the direct relationship between gradients and the perceived …

A system and method for encoding multimedia Video is described. As video is encoded a
quantization parameter is selected for each macroblock. As described herein, the quan …

The spatial-domain intra prediction scheme of H. 264 has high computational complexity,
especially for the High Profile as it incorporates the additional intra 8× 8 prediction mode. To …

We review the impact of deep-learning technologies on camera architecture. The function of
a camera is first to capture visual information and second to form an image. Conventionally …

In video-based point cloud compression (V-PCC), the 3D dynamic point cloud sequence is
projected into 2D sequences for compression by utilizing the mature 2D video encoder. It is …
