A segmentation method based on image enhancement method with wavelet fusion was proposed to segment X-ray mammogram images with low pixel and unclarity. Firstly, a breast X-ray image was pretreated by histogram equalization and median filtering. Then a wavelet fusion algorithm with the rule of taking large low frequency energy and high-frequency variance was applied to the pretreated image, subsequently producing an enhanced image. Secondly, an improved live-wire interactive segmentation algorithm with qualification to make the shortest path search was used to divide suspicious masses on the enhanced image. Related experiments were carried out on typical data-sources that came from the Mammographic Image Analysis Society mini-database and clinical mammography images, and the results indicated that the algorithm have good effect on image enhancement and segmentation.
