Hello everyone i have a code which draws a line in a pic and takes the fft of the profile of the line,does anyone know how can i take multiple parallel lines to the original line and find the ffts of all the profiles of the pixels and find the averge fft?

Could you imrotate() the image so that it's rows are parallel to your line? Then, the operation would reduce to
fft( mean( imrotate(yourImage,angle) ,1) )

It is taking the FFT of the average row. The averaging does not distinguish between foreground and background.
