=========================================================
Requirement :
1. OpenCV-devel 2.3.1+
2. g++
3. OpenMP-devel

File :
1. Library --> imgcomp.h
2. Main Program --> main.cpp

library format:
float imgcomp(char* filename1, char* filename2, int CompareValueType)

Predefined constant :
Constants for CompareValueType : IMGCOMP_PSNR, IMGCOMP_SNR, IMGCOMP_SSIM
Constants for Output : IMGCOMP_PICNOTEQUAL, IMGCOMP_FILE1FAIL, IMGCOMP_FILE2FAIL

Compile with: 
$ g++ -I/usr/include/opencv -lopencv_core -lopencv_highgui -lopencv_ml -lm main.cpp -fopenmp -o imgcomp
(based on Fedora 16 Linux. For other distribution please specify correct include directory for openCV)

Example (command line usage) :
$ imgcomp lena_color_512.tif lenna_noisy_50.jpg

Example (function usage) :
imgcomp("lena_color_512.tif", "lenna_noisy_50.jpg", IMGCOMP_PSNR)
will return command for PSNR of two pictures.
