ABSTRACT:
A coding and decoding method includes the step of a) classifying an input multi-level image into edge parts and non-edge parts according to edge degree thereof; b) coding the input multi-level image according to a coding scheme different between the edge parts and non-edge parts; and c) decoding coded data according to a linear interpolation scheme, a cubic-function convolution scheme or an interpolation scheme having smoothing performance for generating pixel values included in the non-edge part.
