In this talk we will review some recent approaches for improving denoising results, in the particular case of photographic images. This includes denoising a transformed version of the image rather than processing the image data directly, ensuring the image follows the noise model assumed by the denoising algorithm, and optimizing the parameters of the denoising method according to visual appearance, not to image quality metrics.
