Abstract: It is widely accepted in the medical community that breast tissue density is an important risk factor for the development of breast cancer. Thus, the development of reliable automatic methods for classification of breast tissue is justified and necessary. Recent studies have shown that their sensitivity is significantly decreased as the density of the breast is increased. The internal density of the breast is a parameter that clearly affects the performance of segmentation algorithms in defining abnormal regions. In this study, the breast region was extracted from background, and pectoral muscle was suppressed. We review different methods for computing tissue density parameter. An attempt was made to combine the individual scores from different techniques in order to compensate their individual weaknesses and to preserve their strength. We also present and exhaustively evaluate algorithms using computer vision techniques. We obtained accuracy as high as 94% of automatic agreement classification.
