A Survey on Mammogram Enhancement and Denoising Techniques

Breast cancer is one of the leading causes of the cancer death for women in the world. Mammography is at present the best available technique for early detection of breast cancer. The most common breast abnormalities that may indicate breast cancer are masses and calcifications. However, the typical diagnostic signs are difficult to be detected because mammograms are low contrast and noisy images. There are many enhancement techniques proposed by different authors in order to help radiologists to provide an accurate diagnosis in screening programs. This paper provides survey about some of the techniques applied for mammogram image enhancement.
