Most texts nowadays are produced in an electronic form by the use of systems which provide text processing facilities but also linguistic facilities such as spelling checkers, on-line lexicons and even syntactic checkers. We think that a computer-aided writing system must be designed as a complete environment for the production, maintenance, edition and communication of texts. This implies for ...

It is the intention of the author that this report serve as a strategic review of the potential for image processing techniques to aid the detection and classification of underwater mines and mine-like objects in various modes of sonar imagery. Image processing techniques to improve the performance of mine hunting operations using sector-scan, side-scan and the Acoustic Mine Imaging (AMI) proje...

We present a novel pipeline for computer-aided detection (CAD) of colonic polyps by integrating texture analysis with volume rendering and conformal colon flattening. Using our method, the 3D polyp automatic detection problem is converted into a 2D image analysis problem. The colon surface is first segmented and extracted from the CT data set of the abdomen, which is then mapped to a 2D rectang...

A system that automatically identifies suspicious regions in mammograms could be useful to radiologists by drawing attention to abnormalities that may otherwise have been overlooked. Two detection algorithms are described; one based on the combination of evidence from multiple cue generators and the other based on fuzzy pyramid linking. The latter algorithm proved to be the more effective for l...

In this paper, we propose a formal model of the objects involved in a class of scheduling problems, namely in the classroom scheduling in universities which allow a certain degree of liberty in their curricula. Using the formal model, we present efficient algorithms for the detection of collisions of the involved objects and for the inference of a tree-like navigational structure in an interact...

Computer aided detection (CAD) is a technology designed to decrease observational oversights--and thus the false negative rates--of physicians interpreting medical images. Prospective clinical studies have demonstrated an increase in breast cancer detection with CAD assistance. This overview briefly describes the metrics that have been used to define CAD system performance.

Colon cancer is one of the leading causes of cancer deaths in the developed countries. Most colon cancers can be prevented if precursor colon polyps are detected and removed. Virtual colonoscopy, or CT colonography, has shown promise to be the future screening tool for polyp detection, with a number of studies performed at academic institutions showing high sensitivity and specificity. Two main...

A computer-aided detection (CAD) system for the identification of

We have developed a computer-aided detection (CAD) system to detect clustered microcalcification automatically on full-field digital mammograms (FFDMs) and a CAD system for screen-film mammograms (SFMs). The two systems used the same computer vision algorithms but their false positive (FP) classifiers were trained separately with sample images of each modality. In this study, we compared the pe...
