Abstract

This invention discloses an image processing method and an image processing device for filtering images. The image processing method includes the following steps: (A) generating a weight for each reference pixel, the image including multiple reference pixels and the magnitude of the weight being associated with a similarity between the reference pixel to which the weight corresponds and a target pixel; and (B) performing an infinite impulse response (IIR) filtering operation according to the weights, a pixel value of the target pixel, and the pixel values of the reference pixels to obtain an IIR-filtered value of the target pixel.
