ICT image enhancement method based on wavelet transform and redistributed histograms

A hew ICT image enhancement method is presented based on the wavelet transform and redistributed histograms to overcome the defect of existing ambiguous target in conventional method. First, analyze the image using wavelet transform, the suspect lacuna region of interest(ROI) was detected by using higher order statistic feature and morphology operator, so the ROI was defined as foreground image, and the rest was background image. Then a histogram redistribution scheme was adapted to process the foreground and background section separately. Compared with general enhancing methods, it can process image more clearly in the region of target interest. The good performance in preprocess step of ICT image lacuna detection system proves that this method is valid and feasible.
