Hi,
I was wondering if there a way to plot brightness intensity curve of rgb image so that I could observe the changes between two sequential images graphically?

rgb2gray() gives you brightness of each pixel. Perhaps you want to create a histogram from the results.

See my RGB histogram demo, attached. It goes through all the images in the folder plotting the histograms for each color channel.
