Image Processing: Break straight lines
3 views (last 30 days)
I have an edge image of a square, and would like to treat it as 4 separate lines: 2 horizontal and 2 vertical. Is there a way to disconnect the corner edges so that I can process each side individually?
Do you have the Image Processing Toolbox? See the help on corner():
Find corner points in image
C = corner(I) detects corners in image I and returns them in matrix C.
C = corner(I, method) detects corners in image I using the specified method.
C = corner(I, N) detects corners in image I and returns a maximum of N corners.
C = corner(I, method, N) detects corners using the specified method and maximum number of corners.
C = corner(..., Name,Value) specifies parameters and corresponding values that control various aspects of the corner detection algorithm.
