The serial number generally refers to the number of a certain activity participant, and can also refer to the code of the bank. The serial number on the check is used as an important voucher for later retrieval and positioning samples. It is easily defaced when it is covered by a seal, resulting in The serial number is difficult to identify

Abstract

The embodiment of the invention discloses an image processing method, device and terminal and a computer readable storage medium. The method comprises the steps: obtaining a processing region, comprising a specific character string, in a to-be-processed image, and performing the contrast enhancement processing of the processing region to obtain a first processing image; obtaining the colors of pixels in the first processing image, and judging whether there is a damage in a first processing image or not according to the colors of the pixels; removing the damage in the first processing image according to a preset processing model when there is the damage in the first processing image, and performing the character recognition according to the image after the damage is removed. The method canremove the interference caused by the damage in a character recognition process, improves the character recognition accuracy, can resist various types of damages in the actual samples, and is high inrecognition stability.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method, device, terminal and computer-readable storage medium. Background technique [0002] With the rapid development of social intelligence, the application of Optical Character Recognition (OCR) is becoming more and more extensive. OCR refers to the use of electronic equipment to detect and identify printed characters, and determine its shape by detecting dark and bright patterns, and then The process of translating shapes into computer text using character recognition methods. The serial number generally refers to the number of a certain activity participant, and can also refer to the code of the bank. The serial number on the check is used as an important voucher for later retrieval and positioning samples. It is easily defaced when it is covered by a seal, resulting in The serial number is difficult to identify. Contents of the invention ...
