WebJan 18, 2024 · 1 Answer Sorted by: 2 Don't apply the Canny edge detector to your image. You are detecting lines in the edge image, which will give you a line for each edge in your input image. Your input image contains lines that you want to detect, apply Hough directly to it. WebThis MATLAB function locates peaks in the Hough transform matrix, H, generated by the hough function.

WebFind the peaks in the Hough transform matrix, H, using the houghpeaks function. P = houghpeaks (H,5, 'threshold' ,ceil (0.3*max (H (:)))); Superimpose a plot on the image of the transform that identifies the peaks. x = theta (P (:,2)); y = rho (P (:,1)); plot (x,y, 's', 'color', 'black' ); Find lines in the image using the houghlines function.

WebSRN For the multi-scale Hough transform, it is a divisor for the distance resolution Rho. The coarse accumulator distance resolution is Rho and the accurate accumulator resolution is Rho/SRN. If both SRN=0 and STN=0, the classical Hough transform is used. Otherwise, both these parameters should be positive. default 0.
