TLDR
The hybrid system for detecting masses in mammographic images is discussed, which uses texture features, decision trees, and a multiresolution Markov random field model to analyze mammograms.
Abstract
This paper discusses the hybrid system for detecting masses in mammographic images. The proposed approach analyzes mammograms in three major steps. First, a global segmentation method is applied to find regions of interest. This step uses texture features, decision trees, and a multiresolution Markov random field model. The second stage works on the output of the previous algorithm. Here, a combination of three different local segmentation methods is used, and then, some relevant features are extracted. Some of them refer to the shape of the object; others are texture parameters. The final decision is made using a linear combination of these features

Data mining technique for automated diagnosis of glaucoma using higher order spectra and wavelet energy features

TL;DR: A novel integrated index called Glaucoma Risk Index (GRI) is proposed which is made up of HOS and DWT features, to diagnose the unknown class using a single feature and it is hoped that this GRI will aid clinicians to make a faster glaucomA diagnosis during the mass screening of normal/glaucoman images.

Comparison of the Performance of Screening Mammography, Physical Examination, and Breast US and Evaluation of Factors that Influence Them: An Analysis of 27,825 Patient Evaluations

TL;DR: Mammographic sensitivity for breast cancer declines significantly with increasing breast density and is independently higher in older women with dense breasts, which significantly increases detection of small cancers and depicts significantly more cancers and at smaller size and lower stage than does PE, which detects independently extremely few cancers.

Detection of stellate distortions in mammograms

TL;DR: A method is described to detect stellate patterns in mammograms based on statistical analysis of a map of pixel orientations, which provides an estimate of the orientation of this structure, whereas in other cases the image noise will generate a random orientation.

Markov random field for tumor detection in digital mammography

TL;DR: The algorithm was notably successful in the detection of minimal cancers manifested by masses, and an extensive study of the effects of the algorithm's parameters on its sensitivity and specificity was performed in order to optimize the method for a clinical, observer performance study.
