Problems solved by technology

The difficulty of the second step is that because different people's handwriting styles are very different, and there are cases of continuous strokes, it is difficult to achieve 100% accurate character segmentation
The difficulty of the third step is to obtain training data with sufficient sample size

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as Figure 1-5 As shown, the method of the present invention for identifying capitalized amounts in bills comprises the steps of:

[0021] S1, using the method of elastic deformation to generate a given image of Chinese characters containing multiple uppercase numbers, and generate images of uppercase numbers in different styles imitating handwriting;

[0022] That is, for a given image containing a single uppercase Chinese character, use the elastic deformation method to generate more images with similar styles, such as figure 1 Shown is the resulting image.

[0023] Specifically, for each pixel point (x, y), two random numbers Δx and Δy are generated, which respective...

Abstract

The invention discloses a method for identifying capitalized amounts in bills, which comprises the steps of generating images of multiple capitalized numerals imitating handwriting in different styles for a given image of Chinese characters containing a plurality of capitalized numerals by using an elastic deformation method; For the initial segmentation of multiple image projections, choose to separate the characters by finding the connected area: or use the regional gradient image, and convolution operation with the convolution kernel, use the pixel point gradient, through the formed segmentation path to separate the characters in the sub-area Separated to finally form a character segmentation algorithm; during recognition, use this character segmentation algorithm to segment the uppercase image of the number in the bill to form a single character and then input it into the neural network recognition model for character recognition. The invention realizes the fast division of the capitalized amount in handwriting.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method for recognizing capitalized amounts in bills. Background technique [0002] In bill authentication and recognition, for the bill image, it is necessary to recognize the uppercase amount in handwriting, such as "zero, one, two, three, four, five, six, seven, eight, nine, ten" and so on. The recognition process is generally divided into three steps: 1. Cut out the approximate range containing the handwritten amount in the image. 2. Divide the handwritten amount into individual characters. 3. Recognize each character with a neural network. [0003] The first step is relatively simple, because the relative position of the handwritten amount in the note is fixed. The difficulty of the second step is that because different people's handwriting styles are very different, and there are cases of continuous strokes, it is difficult to achieve 100% accuracy in characte...
