This paper describes the recognition of container code characters. The system has to deal with outdoor images which usually have damaged characters and obtain an answer in real time. Tophat transformation, equalization and adaptive cropping have been applied so as to reduce the noise and correct the inclusion box. The training corpus is artificially grown(More)
Thioredoxins are proteins that participate in different cellular processes via redox-mediated reactions. For humans, we have recently described two novel members of this family that display a male germ cell specific expression pattern, named spermatid specific thioredoxin (Sptrx-1 and Sptrx-2 respectively). We report here the cloning and characterization of(More)
In the yeast Xanthophyllomyces dendrorhous the genes idi, crtE, crtYB, crtl and ast are involved in the biosynthesis of astaxanthin from isopentenyl pyrophosphate. The carotenoid production and the kinetics of mRNA expression of structural genes controlling the carotenogenesis in a wild-type ATCC 24230 and in carotenoid overproducer deregulated atxS2(More)
Data projection is a commonly used technique applied to analyse high dimensional data. In the present work, we propose a new data projection method that uses genetic algorithms to find linear projections , providing meaningful representations of the original data. The proposed technique is compared with well known methods as Principal Components Analysis(More)
In this work, two new techniques for non-linear feature extraction are presented. In these techniques, new features are obtained as radial projections of the original measurements. Radial projections are a particular kind of second order transformations that show interesting properties: they capture the local structure of the data and reduce dramatically(More)
