1. AN ALGORITHM FOR CURVE RECONSTRUCTION FROM SPARSE POINTS / UM ALGORITMO PARA RECONSTRUÇÃO DE CURVAS A PARTIR DE PONTOS ESPARSOS
Curve and surface reconstruction from sparse data has been recognized as an important problem in computer graphics. Non structured data points (i.e., a set of points with no knowledge of connectivity and proximity) together with the existence of noise make this problem quite difficult. In order to solve it, several techniques have been proposed, such as, som

2. HANDWRITING RECOGNITION / RECONHECIMENTO DE CARACTERES MANUSCRITOS
This work introduces an image processing methodology that, associated with a multi-level neural network of perceptrons, is able to isolate and recognize cursive handwritten characters. The character isolation technique makes use of fundamental geometric and topological aspectos of the characters. The work describe procedures to extract the characters skeleto
