Image coding for archiving mammograms

This study is a continuation of the work presented previously. We develop the storage aspect of x-ray images of the breast after processing them with an adaptive discrete cosine transform (DCT) coding method. The decoded images are analyzed by experts. The analysis consists to compare the original and decoded mammograms using keywords, i.e., stellate opacity with short or long spicules and with low or high contrast. A real time coding allows experts to choose the optimal coding rate before storage.
