Hi I am looking to create a bounding box for a region of an RGB images.
I have tried things such as impoly and regionprops, both which are getting me excatly what i need, or maybe im going about it the wrong way.
I basically what the create a function where for a specific region > using a bounding box to select this area, tell me all the values of the pixels in the red, green and blue channels then the variance of them individually.
Can anyone provided code/knowledge on this approach.
Thanks,
Erin

When you have a bounding box (which might have been created based upon grayscale or other 2D analysis), you can imcrop() the RGB image by that bounding box. The rest is just indexing and calling var()
