Enhancement of Micro Calcifications in Mammograms
نویسندگان
چکیده
Mammogram enhancement is required as an early step to detect the breast cancer. Since the calcification area is dark and images have low contrast, it results in difficulty in image enhancement. Various techniques have been developed till date based upon multi-scale morphology and wavelet transformations. Herein, a new enhancement algorithm has been developed based upon multi-scale morphology. The two parameters dilation and erosion have been scaled. The contrast and brightness of the mammogram images is adjusted and then proposed threshold value is applied. The mini MIAS database is used to check the performance of the proposed algorithm and comparing it with the existing techniques.

Quantitative analysis of morphological techniques for automatic classification of micro-calcifications in digitized mammograms
In this paper we present an evaluation of four different algorithms based on Mathematical Morphology, to detect the occurrence of individual micro-calcifications in digitized mammogram images from the mini-MIAS database. A morphological algorithm based on contrast enhancement operator followed by extended maxima thresholding retrieved most of micro-calcifications. In order to reduce the number ...

متن کاملContrast 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 Boosting Based Approach for Automatic Micro-calcification Detection
In this paper we present a boosting based approach for automatic detection of micro-calcifications in mammographic images. Our proposal is based on using local features extracted from a bank of filters for obtaining a description of the different micro-calcifications morphology. The approach performs an initial training step in order to automatically learn and select the most salient features, ...

The purpose of this study is to describe a method that allows the calculation of a contrast-detail curve for a particular system configuration using simulated micro calcifications into clinical mammograms. We made use of simulated templates of micro calcifications and adjusted their x-ray transmission coefficients and resolution to the properties of the mammographic system under consideration (...
