Abstract
An image denoising method and terminal, where the method includes acquiring image data of an image, performing wavelet decomposition on at least one component of three components of the image data to obtain a high frequency wavelet coefficient and a low frequency wavelet coefficient of each component, performing recursive denoising on the low frequency wavelet coefficient of each component in at least one direction, to obtain a denoised low frequency wavelet coefficient of each component, performing wavelet reconstruction according to the high frequency wavelet coefficient of each component and the denoised low frequency wavelet coefficient of each component, to obtain at least one denoised component, and obtaining denoised image data.
