I get only a gray scale image like this from IR camera and I need to write a code that would detect ONLY LEAVES from each plant.

I have no idea what sort of algorithms should I go for in order to that because of complex background. Any suggestions on what I should look for would be greatly appreciated.

You could use image analysis. If the leaves are a temperature different than the rest of the scene, simply threshold and call regionprops().

See my Image Segmentation Tutorial for a full demo. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

The colors only doesn’t mean anything. The goal was to find the temperature difference in leaves using infrared camera. Which gives out only grey scale images. And as my background was complex. Image analyst gave an idea to combine with RGB camera. Do the image registration and mask for green so that I can find respective temperature pixels from IR camera.
