CONSTANT QUALITY CONTROL OF WYNER-ZIV FRAMES IN DCT DOMAIN DISTRIBUTED VIDEO CODING
Distributed video coding Constant quality control Greedy algorithm Adaptive uniform quantizer
font style='font-size:12px;'>
2013/7/24
For most DCT domain distributed video coding systems, xed uniform quan-tizers are used to quantize all Wyner-Ziv (WZ) frames. However, it leads to uctuantvideo quality because the WZ frame quality is...
