Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0046] The invention discloses an edge detection method at any angle, which obtains the gray value of the image to be detected, and then uses several pixel lines at different angles to scan the above image, and respectively extracts the gray values of the pixel points corresponding to the above several pixel lines. Degree value, and store it as a matrix, and the obtained matrix is respectively compared with the first order derivative f of the Gaussian function σ (x) Perform convolution operation, then take the absolute value of the result of the convolution operation, and take the local maximum value of the absolute value; in the matrix corresponding to all the two-dimensional pixels of the image to be detected, the ob...
