Abstract
A paper identifying method and a related device, used for accurately identifying soilage conditions of paper according to the recency degree of the paper. The method in an embodiment of the present invention comprises: obtaining a pixel gray value group of an image of input paper, the pixel gray value group being a combination of gray values of sampled pixels of a specified region of the input paper; obtaining an average value of gray values of all pixels in the pixel gray value group, and using same as a first average gray value; comparing the first average gray value with a recency threshold to determine the recency level of the input paper; obtaining the soilage depth of each of N regions of the input paper, the N being an integer greater than or equal to 1; and determining the soilage level of the input paper according to the soilage depth of the N regions, the region area and a soilage threshold, the soilage threshold corresponding to the recency level.
