In my project i have a set of images. I need to compare them. Each pixel from one image is compared to the pixel at the same location in all other images in the dataset. Aft
You can do it using Catalano Framework. There's several metrics to compare image, including mean square error.
Example:
FastBitmap original = new FastBitmap(bufferedImage1);
FastBitmap reconstructed = new FastBitmap(bufferedImage2);
ObjectiveFidelity o = new ObjectiveFidelity(original, reconstructed);
// Error total
int error = o.getTotalError();
//Mean Square Error
double mse = o.getMSE();
//Signal Noise Ratio
double snr = o.getSNR();
//Peak Signal Noise Ratio
double psnr = o.getPSNR();
All these metrics are based in the book: Computer Imaging: Digital Image Analysis and Processing - Scott E Umbaugh.
Next version (1.3) will contains Derivative SNR.
