A New Multi-Dimensional Wavelet Zero-Tree Encoding Method, Encoder, and Scanning Method for Extremely Low Bitrate

摘要

The present invention discloses a coding method using a new multidimensional wavelet zero tree, and a tree scanning method for an encoder and a very low data rate. The present invention finds a method of eliminating redundancy on the time axis inside the wavelet transform and efficiently transmits data in applications with low data rates by using properties that match the characteristics of human cognitive organs. This allows efficient compression by creating a multidimensional wavelet zero tree that further emphasizes high frequency components in the edges such as edges and high frequency components in the timebase such as large motions, and efficiently transmits data in applications with very low channel rates. have.
