Abstract

The invention discloses a bill correction method based on key point detection, and the method improves the performance of a bill correction algorithm model through the reasonable data enhancement of real data, the increase of training data key point marks and the combination of a high-resolution network HR-Net, and finally achieves the purpose of bill correction.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a key point detection-based bill correction method. Background technique [0002] At present, the number of various types of bills is gradually increasing, so a series of issues such as the positioning, correction, identification and detection of bills have become more and more important. Among them, bill rectification, as a preliminary step of bill identification, plays a crucial role. At present, in the field of bill positioning correction, commonly used methods include traditional image processing methods and deep learning methods. Among them, traditional image processing methods can combine image binarization, edge detection and other technologies to locate bills; and deep learning methods can use methods based on convolutional neural networks. The specific shortcomings of these methods are: traditional image processing methods have strict requirements on sa...
