Hi.
I have represent some plants using branches's ratio and angles with the L-system fractal. These plants belongs to same species but they are different hybrids. So i classified them into two groups. Hybrid 1 and Hybrid 2.
Hybrid 1 group includes these images:

Hybrid 2 group includes those images:
http://oi58.tinypic.com/16geqnn.jpg
http://oi57.tinypic.com/33onldv.jpg
The idea now is to somehow calculate a similarity index to see if images of the same group differs from the images of the other group.
There are lot of topics for image similarity as also and many protocols and methods but i could't find something comparing images like these.
I read about Structural Similarity Index (SSIM) , SIFT technique , Euclidean distance, Mahalonbis distance but i can't decide which one is the right one for my case.
I think that maybe SSIM method might work but if anyone has a different idea or any hint to give me i will be thankful

Hi Nick Fi,
Please try Dynamic Time Warping((DTW) for image similarity index. Its a wonderful similarity technique.

HI Nick Fi
Please go through this link. For converting images into column vector please use this snippet.
clear;clc;close all;
a = imread('first fig');
figure, imshow(a);
b = imread('second fig');
figure, imshow(b);
a = double(a(:));
b = double(b(:));
w=50;
