Abstract

In the present paper, a comparisonbetween classical masks and (odd and even)masks groups for Mycosis Fungoides diseaseSkin image edges detection is performed.The goal is to extract the information known inthe image because it is vital to understand theimage content as the proposed approach is thecomparative edge by masks classical and a newset of Groups masks (odd and even ) whichconsist of 10 masks. The database consists of40 images reprints different stage of theMycosis Fungoides disease Skin images 10images for each stage. The experimental resultsconfirm the effectiveness of the proposedsystem. and confirm the effectiveness of theproposed(odd and even) Groups masks.

Abstract

In the present paper, an importantmathematical transform which is calledGabor transform be used to develop amethod for image compression. Gabortransform is a type of wavelet-basedtransform. It is embedded in the standardcompression algorithm (JPEG2000) as amother wavelet. Based on the obtainedresults we believe that Gabor wavelettransform can provide the optimal resolutionin both the time and frequency domains, aswell as it seems to be the optimal basis toextract local features such as discontinuities.These advantages of Gabor wavelettransform make it an efficient transform forcompression. The proposed compressionsystem is a new approach that achieves ahigh compression ratio with acceptablevisual quality by exploiting the advantagesof Gabor wavelets .The simulation resultsshow that the proposed model gives a goodcompression images that could becompetitive to JPEG2000 using Haarwavelet.
