Embodiment 1
[0064] Such as figure 1 As shown, the bionic contour detection method based on X, Y parallel visual channel responses provided by this embodiment includes the following steps:
[0065] A, input the image to be detected through grayscale processing, and construct the X-type cell and Y-type cell simulation model in the retinal ganglion cells and the outer geniculate body;
[0066] B. Calculation of the initial response value of type X cells:
[0067] The X-type center two-dimensional Gaussian function, the X-type peripheral two-dimensional Gaussian function, and the X-type center peripheral antagonism strength are preset. The spatial standard deviation of the X-type peripheral two-dimensional Gaussian function is greater than the X-type center two-dimensional Gaussian function. For each pixel, The X-type central two-dimensional Gaussian function and the X-type peripheral two-dimensional Gaussian function are used to perform two-dimensional Gaussian filtering on the gray value, ...
