Image Coding and Decoding by Using Wavelet Transform

Abstract

Human perception of image is, in part, reliant on detection of formant frequencies and their transitions times. Subjects utilize formant transition length to categorizei looks. Image coding and decoding by wavelet is an active area of image research and this done by take the wavelet transform to send the information the frequency domain ,impossible to recognize responsible to the filters of the program and in the same manner but in the reverse form take the inverse wavelet transform and return to the time domain .
