A low-complexity video coder based on the Discrete Walsh Hadamard Transform
, 2000 This paper reports the results obtained of applying the Discrete Walsh-Hadamard Transform (DWHT) in a video coding scheme. It will be shown that for low bitrate applications the DWHT can reach performances analogous to those obtained with the Discrete ...
