Image Compression on the Basis of Edge Compensation in Wavelet Transform

摘要

A new compression method consisting in multiscale separation of image into edge and background, is suggested. Edge selection is made within each scale on the basis of a symmetrical low-frequency filter and the background is represented by wavelet coefficients. It is demonstrated, that this method, compared to the wavelet transform, is faster and enables one to obtain a higher ratio of image compression.
