convert a pixel intensity of gray-scale image to 1D type Signal
3 views (last 30 days)
I'm going to use a 1D wavelet for controlling the surface quality according to the taken images of the surface of the product. then I try to find the pixel intensity along the scanned line. but the input for the 1D wavelet should be the 1D signal.
I used "improfile" function to find a pixel intensity on a specific scanned line. then I have an intensity-distance profile.
now my question is: how can I convert this profile to a 1D signal inorder to use in wavelet?

The algorithm for converting RGB values to Intensity values is
This algorithm converts a n-by-1-by-3 vector into a n-by-1 vector
