摘要：
In this paper, we propose an automatic parameter free technique for efficient detection of microcalcifications. First, the nonhomogeneous background is suppressed by performing morphological filtering operation on mammographic image. The resultant image is subjected to entropy-based thresholding to detect microcalcifications. The efficacy of the algorithm is demonstrated through the experimental results.
