A known problem in video streaming is that loss of a packet usually results into loss of a whole video frame. Error concealment is an effective way to solve this problem. A fast interactive anti-error algorithm based on motion tracking which suits for H.264 is proposed. In this algorithm, decoder firstly detects the error, and position of error blocks is feed back to encoder. Then encoder decides...
H.264 video coding standard can achieve considerably higher coding efficiency than previous standards. However, this comes at a cost in considerably increased complexity at the encoder and thus increases the difficulty in hardware implementation. The computation complexity is mainly due to motion estimation in combination of variable block sizes and multi-reference frames. With the initialized searching...
The goal of motion estimation design is to minimize the amount of coded information (residual frame and model information), whilst keeping the computational complexity of motion estimation and compensation to an acceptable limit. This paper introduce efficient fast motion estimation algorithms based on polynomial model to reduce the high computational demands of the H.264 video encoder, and these...
