Dry-cured Iberian pig products are some of the most valuables meat products in Spain. Visually discernible features of fat and lean, such as marbling, have an effect on the acceptability of these products. Marbling properties include the amount and spatial distribution of intramuscular fat streaks. Thresholding techniques are the simplest and most widely used for image segmentation, but pay no attention...
Active Contours are a widely used Pattern Recognition technique. Classical Active Contours are curves evolutionate by minimizing an energy function. However, they can detect only one o bject within an image with several objects, and the solution is highly dependent on parameters in its formulation. A solution can be found in Geodesic Active Contours (GAC). We have developed a version of this technique...
Active Contours constitute a widely used Pattern Recognition technique. Classical active contours are based on different methodologies. This paper reviews the algorithm paradigms most frequently utilized in active contours (variational calculus, dynamic programming and greedy algorithm) in a practical application, comparing chemical data with computer vision results. An experiment has been designed...
Immunoperoxidase labeling was performed in histological sections from rat brain harvested during acute (1030 days), clinically inapparent (90270 days) and late (450540 days) stages of Junin virus-induced neurological disease. In frontoparietal cortex, count of viral antigen (+) neurons peaked during the acute period (27.76.8), dropped within the intermediate (4.84.0 to 1.41.1) and increased (7.64...
