Comparación de filtros para el análisis del espectro espacial bidimensional de Fourier, en el proceso de digitalización 3D

In this paper, a comparison between three different filters in the 3D scanning processes by Fourier Transform two-dimensional. The implementation and comparison about the filter by threshold, morphological filtering like rectangle and elliptic, the representation about the filters are in a binary mask and it is multiplied by the spectrum of Fourier Transform two-dimensional, with this process the frequencies are eliminated and the new scene shows less noise than the original scene. To compeer we used two objects a manikin and a bat figure, the different filters are applied and the results are compared. In the filtering step also we filter the one pixel about f0 to get a uniform scene.
