Patent attributes
A system and a method for processing images are provided. The method may include one or more of the following operations. An image including a plurality of channels and a plurality of pixels may be obtained, each pixel having a pixel value corresponding to one of the plurality of channels. One of the plurality of pixels may be selected as a pixel of interest, and the corresponding channel of the pixel value of the pixel of interest may be designated as a target channel. A plurality of pixels proximate to the pixel of interest may include at least two first reference pixels. For each first reference pixel, a pseudo pixel value for the target channel of the first reference pixel may be determined. Whether the image is a deteriorated image may be determined at least based on the pixel value of the pixel of interest and the determined pseudo pixel values.
