DCT Coefficient-Based Error Detection Technique for Compressed Video Stream
: In the process of transmission of digital encoded video bit streams over physical network, the data is corrupted by random bit errors, which has a several effect on the decoded v...

Beamforming matrix quantization with variable feedback rate
: We propose an improved beamforming matrix compression by Givens Rotation with the use of variable feedback rate. The variable feedback rate means that the number of bits used to ...

Object-Based Video Coding Using Pixel State Analysis
In archiving video for surveillance, frame-based coding has been used and it makes storage size large because the whole image is stored even if there is no object in the image. On...
