A Fuzzy-Rule Based Algorithm for Contrast Enhancement of Mammograms Breast Masses
نویسندگان
چکیده
Using fuzzy set theory, we present a fuzzy rule-based algorithm to perform contrast enhancement for digital mammography breast masses. Compared to the well-known histogram equalization enhancement technique, fuzzy rule-based enhancement is able to represent knowledge in a comprehensible way. Four measures of quantifying enhancement in digital mammograms have been introduced. Each measure is based on the statistical information obtained from the labeled region of interest and a border area surrounding it. The methodology is based on the assumption that target and background areas are accurately specified. To evaluate the performance of the algorithm, 25 images containing masses from the Mammographic Image Analysis Society (MIAS) database were selected.

Contrast Enhancement of Mammograms for Rapid Detection of Microcalcification Clusters
Introduction Breast cancer is one of the most common types of cancer among women. Early detection of breast cancer is the key to reducing the associated mortality rate. The presence of microcalcifications clusters (MCCs) is one of the earliest signs of breast cancer. Due to poor imaging contrast of mammograms and noise contamination, radiologists may overlook some diagnostic signs, specially t...
متن کاملA Hybrid System for Detection of Masses in Digitized Mammograms
In this paper, a hybrid segmentation method for detection of masses in digitized mammograms has been developed using three parallel approaches: adaptive thresholding method, Gabor filtering and fuzzy entropy feature as a CAD scheme. The algorithm consists of the following steps: a) Preprocessing of the digitized mammograms including identification of region of interest (ROI) as candidate for ma...
متن کاملSegmentation and Classification of Masses in Digital Mammograms for Diagnosing Breast Cancer
Early diagnosis of breast cancer helps to improve the successful treatment.Mammographic images are obtained from X-ray instrumentation. They are noisy and poor contrast due to ill performance of the hardware systems. Enhancement helps in improving the contrast of mammograms and reduces the false positive findings. Various enhancement techniques are available in image processing for improving th...

This paper is concerned with the development of a novel classifier for automatic mass detection of mammograms, based on contourlet feature extraction in conjunction with statistical and fuzzy classifiers. In this method, mammograms are segmented into regions of interest (ROI) in order to extract features including geometrical and contourlet coefficients. The extracted features benefit from...
