Color image analyses using four deferent transformations (FFT-DCT-DWT-DMWT)

Abstract

The transformation is the process that converts information from the spatial domain of the signal and translating it to another domain. the aim of  this paper is to compeer between four transformations are( discrete Fourier transform ,Discrete Cosine Transforms, Wavelet transform and discrete Multiwavelet transform). And there effective with color image. We determined and apply each transform on the image alone and study the effectiveness such as the noise, enhanesment, brightness, compretion, resolution beside the analyses then retrieving the image by applying the inverse of each transform. The performance of this technique has been done by computer using visual basic 6package.
