Embodiments of this invention include computer-implemented methods for use of Haar wavelet transforms (HWT) to pre-process video frames that can then be compressed using a codec to produce a compressed video frame. A compressed video frame can then be transmitted, decompressed, post-processed and displayed in their original size and quality, thereby producing real-time high-quality reproduction of video sequences. Devices can implement methods of this invention and include mainframe computers, desktop computers, personal computers, laptop computers, tablet computers, wireless computers, television sets, set top boxes, cellular telephones, and computer readable media. Computer implemented steps can be easily and efficiently implemented in multicore parallel hardware architectures.
