“…The gray moment edge detection method (Tabatabai and Mitchell, 1984) has been well recognized for subpixel edge detection in terms of one-and two-dimensional data. The rationale behind a gray moment edge localization algorithm is that the edge distribution of an image is in coincidence with its gray moment in contrast to a transparent background.…”

“…For each target the gray values along several rays beginning at the initial center are sampled until a gray value edge is detected. The position of the found edge is further refined to sub-pixel precision using moment preservation 16) . Figure 1 (a) shows an example for a calibration pattern as it appears in the camera.…”

“…A técnica de Canny consiste em calcular os pontos u(x) tais que: ∇ 2 u(∇u, ∇u) = 0, e |∇u(x)|é suficientemente grande. Existem outras diferentes técnicas para determinação das bordas de uma imagem como: as técnicas baseadas em resolução de subpixel [18] ou os modelos estocásticos de uma imagem. Para maiores detalhes ver [10].…”
