Abstract

The embodiment of the invention discloses a method and a device for determining whether a medium is new or old, computer equipment and a storage medium. The method comprises the following steps: obtaining a gray histogram corresponding to a target medium according to a target front image and a target back image; obtaining a first gray value corresponding to a first region and a second gray value corresponding to a second region according to the gray histogram, wherein the first region and the second region are image regions in the target front image and the target back image, and the gray value of the pixel points in the first area is greater than that of the pixel points in the second area; according to a first gray value corresponding to the first region and a second gray value corresponding to the second region, obtaining a gray difference value between the first region and the second region; and determining whether the target medium is new or old according to the gray difference value of the first region and the second region. According to the invention, the misjudgment probability can be reduced.

Description

technical field [0001] The present invention relates to the technical field of old and new medium detection, in particular to a method, device, computer equipment and storage medium for determining old and new medium. Background technique [0002] Existing detection equipment for sheet-like media usually has the function of detecting old and new media. For example, automatic teller machines, or bill equipment, can detect the old and new condition of thin banknotes or bills. [0003] However, the existing method for determining the old and new media is mainly realized by judging the average gray value of the highlighted area of ​​the medium. The lower the average gray value of the highlighted area, the older the medium, and the higher the average gray value of the highlighted area. The newer the media. For banknotes, the highlighted area is usually the rectangular area above the serial number in the obverse image of the banknote. [0004] It can be seen that in the existin...
