Hi
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?
Thank you

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
Additional Information about the color space conversion algorithm can be found here

Dear Rohit
Thanks for your reply
Are you suggesting to use this method for getting intensity instead of my method?
Because I already have the intensity results and my problem is converting the pixel intensity to a 1D signal.
