DMelt:Image/4 Image Analysis
DMelt supports image analysis and image comparisons. You can make histograms using image data, and calculate many values that characterize images, such as Peak signal-to-noise ratio, often abbreviated PSNR, or Signal-to-noise ratio (SNR). See the definitions Signal-to-noise ratio (imaging) and Peak signal-to-noise_ratio.
Look at the examples shown below:
