Hi,
I have a program that gets an RGB image, transforms it to grayscale and then extracts its red and green channel. I need to get the same image, convert it to Cielab color space and then transform it to grayscale and then extract the red and green channels too.
I already converted my RGB image by using commands makecform and applycform. I saw that I can extract Lab "channels" by using (:,:,1), (:,:,2) and (:,:,3), I mean, by changing the last argument in there. So, my questions are:
1) Is the L "channel" the CieLab image already in grayscale or should I perform something else to get it? 2) Is it possible to get separated red and green channels from A "channel" as I got from the image in RGB color space?
Thank you so much!
