27. A Method for Interactive Shape Detection in Cattle Images Using Genetic Algorithms.

Abstract

Segmentation methods based on deformable models have proved to be successful with difficult images, particularly those using genetic algorithms to minimize the energy function. Nevertheless, they are normally conceived as fully automatic, and not always generate satisfactory results. In this work, a method to include the information of fixed points whithin a contour detection system using point distribution models and genetic algorithms is presented. Also, an interactive scheme is proposed to take advantage of this technique. The method has been tested against a database of 93 cattle images, with a significant improvement in the success rate of the detections, from 61% up to 95%. [ABSTRACT FROM AUTHOR]

28. Neural-networks-based edges selector for boundary extraction problems

*ARTIFICIAL neural networks, *BOUNDARY value problems, *LIVESTOCK, *DIGITAL images
Abstract

In the present work, a neural-networks-based system is presented that makes it possible to reduce, when generating edge maps to be used in an object boundary detection problem, the number of edges that are not due to the object itself, but to the background. Starting from a conventional edge detection, the selection is carried out by a neural-networks-based classifier, which is trained using examples. As a test for the system, the application to bovine livestock images (from which we want to extract the boundary of the animal) is presented. [Copyright &y& Elsevier]
