I think the best way is to just try it and see. I can't tell just by looking at it. If you want further explanation contact the author and ask that more comments be put in. It's asking quite a lot to ask us to explain this long program.
Also, please just attach the m-file or else format it properly. See the formatting tutorial http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Color may not be so reliable since I imagine there could be a range of colors in a given species that it not unique to that one species - lots of other trees and bushes will have that color. So I think you need to look at shape, like Fourier descriptors. See morphometrics http://en.wikipedia.org/wiki/Morphometrics.
Sorry I don't have any programs that do that and it's too major of a project to write a leaf identification program for you - it's not something I can bang out in 5 minutes or less like the other demos I upload here.

yup :) thats true we cant use the color because it is not very reliable we focused more on shape and texture.
no i dont want you to create a program for me :) i just want to know the flow of the program that i uploaded :) i hope you can now see the program that i uploaded :) and if it is possible add some comment in the code so i can understand it :) thankyou so much by the way:)
