A Two-Channel Overlapped Block Transform for Image Compression

In this project, a new two-channel overlapped block transform is introduced by pre filtering the Haar transform. The pre filtering employs plane rotations with one single rotation angle to achieve high Computational efficiency. The resulting transform is equivalent to a periodically time-varying (PTV) filter Bank.
