In depth map coding for 3D video coding systems, coding errors in edges can severely affect the synthesis quality. Edge errors mainly compose of two parts: one is blurring and ringing artifact around sharp edge and the other is fake edge caused by blocking artifact. In this paper, we propose an adaptive depth map filter to remove blocking artifacts while preserving depth edges. The proposed filter...
Real-time encoding of high-definition H.264 video is a challenge to current embedded programmable processors. Emerging stream processing methods supported by most GPUs and programmable processors provide a powerful mechanism to achieve surprising high performance in media/signal processing, which bring an opportunity to deal with this challenge. However, traditional serial CAVLC has highly input-dependent...
Due to the rapid growth of graphics processing unit (GPU) processing capability, using GPU as a coprocessor to assist the central processing unit (CPU) in computing massive data becomes essential. In this paper, we present an efficient block-level parallel algorithm for the variable block size motion estimation (ME) in H.264/AVC with fractional pixel refinement on a computer unified device architecture...
