Method and system for automatically detecting filling color of bill image elements

Abstract

The present invention discloses a method for automatically detecting filling color of bill image elements. The method comprises: collecting a bill image, obtaining a plurality of bill element infrared region images through extraction; carrying out threshold segmentation on each bill element infrared region image; and carrying out filling color detection on a bill element infrared region according to a binary image in each bill element infrared region. The present invention discloses a system for automatically detecting filling color of bill image elements. The system comprises an image collection module, an element region extraction module, a binary value processing module and a filling color detection module. And the system for automatically detecting filling color of bill image elements also comprises a bill image collection unit and a detection unit for filling color of bill image elements. The method and system disclosed by the present invention solve a phenomenon of invalid bills caused by non-standard element filling in a batch bill automated processing process, reduce manual time and effort, improve efficiency, and are applied to the field of image processing.

Description

technical field [0001] The invention relates to the field of image processing, in particular to the detection of the filling color of bill image elements in bill processing. Background technique [0002] When the bill automatic processing system of the bank or unit processes the bills, it is required that the face elements of the bills to be processed must be correct and complete. For example, according to the check filling requirements: when issuing a check, use black ink or carbon ink or use a check printer to fill it out carefully, because the words written with a black pen have the longest preservation time and are the least vulnerable to damage. If the face elements of the bill to be processed are incompletely filled or the face elements are not filled in according to the prescribed pen, subsequent processing or operations cannot be performed. Therefore, how to quickly and effectively detect the completeness and color of the bill image elements? An important research o...

Problems solved by technology

[0003] At present, the standard inspection of the elements of bank bills is generally completed by the business personnel through visual inspection. This detection method is low in efficiency and is not conducive to the batch processing of bills, and the accidental errors caused by human visual inspection are inevitable. ,

[0004] Patented a bill image element integrity detection method and system 201510342110.0 has a solution for the automatic detection of bill image element integrity detection, which can greatly reduce the time of manual bill collection and occasional mistakes, and improve the efficiency of batch bill processing. But there is no solution to the problem of filling in the color of the bill image element
