TLDR
In this article, a method for improving disease diagnosis using contrast enhancement presentation is proposed, which consists of providing an input digital diagnostic image, applying a decomposition filter bank to the input digital image, constructing a tone scale curve from the input image and applying said scale curve to the image to produce a tone-scaled image, generating the contrast weight control signals from the image by extracting the high contrast edge signals at the coarse scale.Abstract:
A method for improving disease diagnosis using contrast enhancement presentation comprising: providing an input digital diagnostic image; applying a decomposition filter bank to the input digital diagnostic image; constructing a tone scale curve from the input digital diagnostic image; applying said tone scale curve to the input digital diagnostic image to produce a tone-scaled image; applying a decomposition filter bank to the tone-scaled image; generating the contrast weight control signals from the input digital diagnostic image by extracting the high contrast edge signals at the coarse scale; adjusting the decomposition outputs from both the input image and the tone-scaled image according to the contrast weight control signals; and applying a reconstruction filter bank to the adjusted signals to produce a contrast enhancement presentation output image.read more

Computer-aided image analysis
TL;DR: In this paper, digitized image data are input into a plurality of subsystems, each subsystem having one or more support vector machines, and each subsystem analyzes the data relevant to a different feature or characteristic found within the image, then the output for all subsystems is input into an overall support vector machine analyzer which combines the data to make a diagnosis, decision or other action which utilizes the knowledge obtained from the image.

Methods and systems for display source light management with rate change control
TL;DR: In this paper, a rate control parameter is used to limit the rate at which the illumination level is varied and image content analysis may be used to determine the value of the rate control parameters.

Method and system of automated detection of lesions in medical images
Dan Rico,Desmond Ryan Chung +1 more
TL;DR: In this article, a system and method for processing medical images is described, where the input medical images are normalized first, utilizing pixel intensities of control point tissues, including subcutaneous fat, to identify regions of common internal characteristics, or blobs, that may represent lesions.

Characterization of Signals From Multiscale Edges
Stéphane Mallat,S. Zhong +1 more
TL;DR: The authors describe an algorithm that reconstructs a close approximation of 1-D and 2-D signals from their multiscale edges and shows that the evolution of wavelet local maxima across scales characterize the local shape of irregular structures.

Analysis of cancers missed at screening mammography.
TL;DR: Analysis of 320 cancers found in a screened population between August 1985 and May 1990 revealed 77 cancers that were "missed" at screening mammography, which occurred in women with denser breasts, were less likely to demonstrate malignant microcalcifications, and were more likely to demonstrating a developing opacity as an indication of cancer.

Visual scanning, pattern recognition and decision-making in pulmonary nodule detection.
TL;DR: Using the assumption that prolonged dwell time indicates intensive processing of visual data, a model was developed for nodule detection that includes four steps: orientation, scanning, pattern recognition and decision-making.

Benefit of independent double reading in a population-based mammography screening program.
TL;DR: Independent double reading does significantly increase sensitivity of mammography screening and, specifically, the effect on breast cancer detection.

Mammographic feature enhancement by multiscale analysis
TL;DR: It is demonstrated that features extracted from multiresolution representations can provide an adaptive mechanism for accomplishing local contrast enhancement and by improving the visualization of breast pathology, one can improve chances of early detection while requiring less time to evaluate mammograms for most patients.
