This is the program for check the Image Similarity Measurement of two image.

programming language: python 
libraries : OpenCV

The output values between 0 and 1, 
where 1 is for total similarity and 0 for total dissimilarity.

useing Structural Similarity Index Measurement (SSIM)


# 1. Import the necessary packages
from skimage.measure import compare_ssim
from PIL import Image 
from resizeimage import resizeimage
import argparse
import imutils
import cv2
import numpy as np



Program Run Command: any one of the following command can use. 

1) python img_similarity_mes.py --first crak1.jpeg --second crak2.jpeg
2) python img_similarity_mes.py --first fruit1.png --second fruits2.png
3) python img_similarity_mes.py --first eyerov2.png --second eyerov3.png
4) python img_similarity_mes.py --first team.png --second team1.png
5) python img_similarity_mes.py --first test3.jpeg --second test4.jpeg


Program Structure:

1.get the two image as input 
2.save these image 
3.resize the saved image
4.covert image to gray scale 
5.removing salt-and-pepper noise using median filter
6.applying Structural Similarity Index and shows the SSIM Score with b/w 0-1
For Total Similarity, SSIM =1
For total dissimilarity, SSIM =0
7.threshold the difference image, and finding contours to obtain the regions of the two input images that differ
8.compute bounding box of the contour and then draw the bounding box on both input images to represent where the two images differ
9.Output :
two image with bounding box and image_Similarity SSIM Score
