Advanced image enhancement method for mammogram analysis

In this paper we introduced the three image processing filtering methods. It will be useful for the detection of micro calcification in mammogram image analysis. The preprocessing method plays a vital role in automatic detection of breast cancer. The introduced three filtering methods are Median, Bilateral and the Inverse transform filter. The filter performance analyzed based on the results produced with the help of PSNR and MSE values. Experimental results found that the Inverse transform filter has given PSNR= 95.37, MSE= 0.00001 with noise density 0.005 for salt-and-pepper, Gaussian, Poisson and speckle noise. Then we can say that this filter is the one of the best filters for medical applications.
