ABSTRACT:
A method and apparatus for coding motion video (images) that produces very low bit rate video representation and minimizes the amount of data needed to be transferred to the decoder. The apparatus comprises a 2-pass segmentation section, a 2-stage motion estimation/compensation section that optionally employs Affine Motion Compensation (AMC), a wavelet transform section, a Zero-Tree Wavelet Quantization (ZTQ) section, a code book, a comparator, a reconstruction section, a coder, a frame memory and an entropy coder.
