Abstract

Decimated wavelet transform have previously been used in detection of breast cancer in mammograms though their use always come with a rigorous drawback due to the absence of translation invariance of the representations and as a result, a large artifacts number is introduced into the reconstruction after the wavelet coefficients are processed. However, an undecimated wavelet transform effectively copes with this drawback since its providence of a redundant representation leads to the exhibition of the translation variance thus improving the enhancement and segmentation results.
