Tratamento de Imagens para ampliação Sem Perda de Localização de Pontos de Referência

The use of high-definition images has, as a rule, high cost while the use of lower resolution images and more affordable cost requires magnification. This paper presents a methodology that involves some math- ematical tools applied to the processing of images, with the objective of enlarging them to avoid the displacement or the deformation of the points on a geo-referenced area in the ori ginal image. In this work, we intend to study multivariate interpo lation, combining the Fourier Series and the Chebyshev polynomials for filtering. In addition, the combination with color-brig htness- intensity correction algorithms show results that enable t he treatment of the problem.
