Embodiment Construction
[0032] An edge detection method for fusing uniform color information and a composite receptive field model, comprising the following steps:
[0033] (1) First, multi-scale sampling is performed on the original color image f(x, y). Preliminary use of 5 scales (including upsampling and downsampling), that is, s∈[-1,0,1,2,3], the scaling factor of image length and width is 2 -s . , then a multi-scale image f(x,y,s) can be obtained. In view of the similarity between the uniform color space and the human visual system perception color mode, after the multi-scale sampling is completed, the multi-scale image is converted to the HSV color space. In order to achieve edge extraction, the multi-scale image f(x, y, s) is respectively operated as follows:
[0034] (2) The present invention uses the luminance component V for edge extraction, adopts the Gabor function to convolve the luminance component V, and obtains the Gabor energy map, which is defined as e σ (x,y,s) to simulate the ...
