Abstract

The aim of that work is to perform a data compression on X-Ray images of the breast in order to store them within an image data base. A block adaptive Discrete Cosine Transform method is proposed. A homogeneous distribution of the degradation in the decoded image is obtained using a thresholding approach depending on the permitted coding error for each processed block. The proposed method is tested on a representative set of mammograms, containing the various breast pathologies. The decoded images are then visually analyzed by two experts.
