Abstract

A denoising parameter determination method, comprising: obtaining multiple denoised images corresponding to an undenoised image; for any of the denoised images: determining a difference between any of the denoised images and the undenoised image to obtain a difference image corresponding to any of the denoised images; determining a difference dispersion degree of the difference image corresponding to any of the denoised images; and performing singular value decomposition on the difference image corresponding to any of the denoised images to obtain a singular value set corresponding to any of the denoised images; and determining a singular value dispersion degree of the singular value set corresponding to any of the denoised images; based on the difference dispersion degrees, the singular value dispersion degrees respectively corresponding to the multiple denoised images, and the parameter value groups respectively corresponding to the multiple denoised images, determining a target parameter value group for image denoising processing.
