Edge method of detection and edge detection device of sub pixel

摘要

Topic Position of the edge of the digital image it specifies.Solutions In inside the picture, zero the pixel position n_{0 which} is crossed is identified and (11), sub pixel position offset a is decided (21). As for this offset, zero it is something between related to interpolation picture and the interpolation kernel in the pixel position which is crossed. Lastly, pixel position from n₀ and sub pixel position offset a, the position t_{0 where} edge position is interpolated is decided (26). In order the edge of model object and to make adjust the edge where it is detected, translation with the edge where object inside the picture is detected and the edge to which model object corresponds [v₁, v₂] is decided and (44), cross correlation with the edge of the model which corresponds with the edge where it is detected, is calculated and (46), translational error [e₁, e₂] is decided (48).
