Image processing using MATLAB: Basic operations

09-06-2017·My two cents: Diagonal lines are found by combining two filters one of which is designed to find vertical and the other horizontal lines. So when you remove one of the filters it produces discontinuities. Therefore the lines on the last image are discontinued (w.r.t the previous image) because the diagonal or vertical parts are removed.

Obtaining opposite diagonal of a matrix in Matlab

16-09-2013·Obtaining opposite diagonal of a matrix in Matlab. Let A be an matrix of size [n,n]. If I want to extract its diagonal, I do diag (A). Actually, I want the opposite diagonal, which would be [A (n,1),A (n-1,2),A (n-2,3),...]. One way to do this is via diag (flipud (A)). However, flipud (A) is quite wasteful and multiplies the time it takes by a ...
