1. Seguimiento automatico de tormentas convectivas por radar
An automatic method for identifying and tracking convective storms by radar is presented, which is applied to two cases of study chosen as days with reports of severity. The method uses as entry CAPPI images of radar reflectivity 3 km height, consecutive in time, and obtained with the system Vesta ver. 5.3.4.5 (Pozas, 2005). For the identification the connec

2. Arquitetura pipeline reconfigurável através de instruções geradas por programação genética para processamento morfológico de imagens digitais utilizando FPGAs / Reconfigurable pipelined architecture through instructions generated by genetic programming for morphological image processing using FPGAs
Mathematical morphology supplies powerful tools for low level image analysis, with applications in robotic vision, visual inspection, medicine, texture analysis and many other areas. Many of the mentioned applications require dedicated hardware for real time execution. The task of designing manually morphological operators for a given application isnot alway

3. Methodology for visual and automatic inspection of cargo in railway cars / Metodologia para inspeção visual e automatica de carga em vagões ferroviarios
Neste trabalho foi desenvolvida uma metodologia para inspeção visual e automática de carga de grãos em vagões ferroviários que utiliza técnicas de processamento de imagens. A metodologia inclui três etapas principais: a localização do vagão na imagem utilizando a transformada de Hough, a descrição da carga usando cor e textura, e a identificaç�

4. Evaluation of the quality of wooden plates through a fuzzy inference system based in adaptative networks. / Avaliação da qualidade de placas de madeira através de um sistema de interferência nebuloso baseado em redes adaptativas.
Automatic visual inspection is an important task for industrial productivity. It could be applied for quality control or for replacing manual work under dangerous or repetitive activity. The classification stage in quality control of the industrial production is often based on the human knowledge. It seems, therefore, to be a great concern to supply an autom

5. Metodologia de inspeção visual utilizando limiar("Threshold") entrópico com aplicações na classificação de placas de madeira / Methodology for visual inspection using entropic threshold with aplications in wooden board classification
The objective of this work was to develop a dedicated computer vision method for the classification of wooden plates used in pencil manufacturing. The process here proposed was idealized looking for a low computational complexity methodology that could be accomplished in VLSI, as for instance using Systolic Computer Architectures made of logic arrays. The pe

6. Automated detection of point mutations using fluorescent sequence trace subtraction.
The final step in the detection of mutations is to determine the sequence of the suspected mutant and to compare it with that of the wild-type, and for this fluorescence-based sequencing instruments are widely used. We describe some simple algorithms forcomparing sequence traces which, as part of our sequence assembly and analysis package, are proving useful

7. Automatic enumeration and characterization of heterogeneous clonal progression in cell transformation.
Most human tumors are clonal in origin, although the cells may be diverse in their properties. Since the tumors evolve through progressive stages over decades of time, it is possible that the conditions that induced the tumor transform many cells, but that selective overgrowth of the fastest growing lead to a clonal population of identified tumor cells. We s
