An improved early detection algorithm for all-zero blocks in H.264 video encoding

An improved algorithm for the early detection of all-zero blocks in H.264 video encoding is proposed in this paper. Based on the theoretical analyzes for the integer transform and quantization in H.264, we derive a sufficient condition under which each quantized coefficient becomes zero. And then, a...
