compare_psnr

skimage.measure.compare_psnr(im_true, im_test, dynamic_range=None) [source]

Compute the peak signal to noise ratio (PSNR) for an image.

Parameters:	im_true : ndarray Ground-truth image. im_test : ndarray Test image. dynamic_range : int The dynamic range of the input image (distance between minimum and maximum possible values). By default, this is estimated from the image data-type.
Returns:	psnr : float The PSNR metric.
