MATLAB: Color matching and comparison

Question

Hey gang,

I am hoping that I can be placed onto the right thought process track. My end-goal is as follows:

• Load an image into MatLab.
• Find an average color value of the loaded image and save that value.
• Compare that color value to a group of other color values, and find which color value matches the one from the image.

So basically, I am wondering if it is possible to find an average color value from an uploaded image? The images that I hope to upload are primarily of the same color (brown), but there will be different shades of brown in that image. I want to compare that image to a group of other images and find which one matches the loaded image best.

Thanks for your help!

You can definitely do this. Check out my Delta E application in my File Exchange. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 The only difference is that after you draw a color in one image you want to apply it to other images instead of the same image.
