WebApr 11, 2024 · An extra loss function must be added to the generator to generate images near the ground truth. In this work, a PSNR served as the loss function of the generator: (6) L psnr G = E x − 10 ⋅ log 10 M A X 2 / M S E y, G x where MAX denotes the maximum pixel value of the image; thus, the final objective function is: (7) L pix 2 pix = min G max D L … WebCompute the peak signal to noise ratio (PSNR) for an image. Parameters: image_true ndarray. Ground-truth image, same shape as im_test. image_test ndarray. Test image. data_range int, optional.
