This research proposes a Coding-Gain-Based (CGB) complexity control method for real-time H.264 video encoding in complexityconstrained systems such as wireless handsets. By allocating more complexity to the encoding tools which have higher coding efficiency, the CGB method is able to maximize the overall coding efficiency of the encoder. key words: video coding, complexity control, power control

Video sequence generally contains a significant amount of statistical and perceptual redundancies. The ultimate goal of video coding is to reduce the average bits to represent the video signal by exploring these redundancies. Typically, the performance of video compression is related to both the amount of redundancy contained in the video data and the efficiency of the actual algorithms used fo...

The visual signal is highly occupied by regions of homogeneous and repetitive patterns known as Textures. Textures have a common property that their similarity highly deviates from point by point comparison, i.e, two textures can look very similar even if they have some shift, rotation and difference in their distribution. In the context of compression, All of the MPEG reference encoders (inclu...

High-efficiency video coding (HEVC) is a new video coding standard being developed by the Joint Collaborative Team on Video Coding. HEVC adopted numerous new tools, such as more flexible data structure representations, which include the coding unit (CU), prediction unit, and transform unit. In the partitioning of the largest coding unit (LCU) into CUs, rate distortion optimization (RDO) is appl...

In Telemedicine applications, for diagnostic purposes, it is essential that the video compression process causes no tangible loss of detail and introduces no noticeable artifacts which could be otherwise misinterpreted as being pathological in nature. On the other hand, due to the limitation of storage and transmission and the huge amount of medical video, high compression ratio is often requir...

As a 3D extension of the High Efficiency Video Coding (HEVC) standard, 3D-HEVC is developed to improve the coding efficiency of multi-view video. However, the improvement of the coding efficiency is obtained at the expense of a computational complexity increase. How to relieve the computational burden of the encoder is becoming a critical problem in applications. In this paper, a fast encoder d...

Due to the popularization of digital image capturing devices, video content is growing in volume every year. To compress the huge amount of data to much smaller capacity so that it can be manipulated with low cost for video conference, broadcasting, online video-on-demand and surveillance system, video coding technology has been developed since 1989. H.264/AVC is the latest international standa...
