1. Implementação paralela do algoritmo iterativo de busca do parâmetro de regularização ótimo para o funcional de Tikhonov no problema de restauração de imagens / Parallel implementation of the iterative algorithm to search the optimal regularization parameter for the Tikhonov functional problem in image restoration
The use of techniques with the functional of Tikhonov in image processing has been widely used in recent years. The basic idea in this process is to modify an initial image using a convolution equation and to find a parameter which minimizes the function in order to obtain an aproximation of the original image. However, a typical problem in this method consi

2. Proposição e avaliação de indicadores de desempenho para algoritmos de restauração de imagens / Proposition and evaluation of different performance indicators for image processing algorithms
The restoration of images acquired with Atomic Force Microscopes (AFM) consists on a very intense research area in nanotechnology. During the acquisition process the AFM images are subjected to the constraints imposed by the experimental apparatus usually presenting poor signal to noise ratios as well as the effects of tip-sample interaction. In order to pro
