A method of encoding a matrix, particularly a matrix for displaying still images or moving images, using wavelet transform.

摘要

The present invention is a method for encoding a plurality of successive layers of an initial matrix into a compression matrix and restoring the compression matrix as a decompression matrix, wherein each cell of the initial matrix includes an initial value; Each cell of the compression matrix includes a respective compressed value corresponding to each of the initial values; for encoding in a method wherein each cell of the decompressed matrix includes each decompressed value corresponding to each of the initial values: 2 × Performing a wavelet transform on the entire matrix over a limited number of levels such that a residual level of size 2 or greater remains; differential encoding of the residual level by obtaining a difference using each value of the residual level; That is, the present invention relates to an encoding method characterized by performing the remaining level compression.
