Embodiment Construction

[0028] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0029] see Figure 1 to Figure 7 , in this embodiment, an image and text recognition and cutting method can be applied to storage devices, and the storage devices include: smart phones, tablet computers, desktop PCs, notebook computers, PDAs, etc., which have the function of recognizing image and text .

[0030] First of all, some nouns that will be involved in this embodiment are explained as follows:

[0031] Binarized image: that is, a binarized image, a digital image with only two possible values ​​for each pixel. It is common to set the gray value of the pixels on the image to 0 or 255, that is, to present the entire image with an obvious black and white effect. The binarization of the image is beneficial to the further proces...

Abstract

The invention relates to the field of image character recognition, in particular to an image character recognition cutting method and a storage device. The method comprises the steps of: obtaining a binary image of an image to be recognized; a binary image being traversed in a preset order, judging whether the gray value of the predetermined end point is equal to the second preset threshold valueby taking the traversed first gray value equal to the first preset threshold value as a starting point and taking the adjacent diagonal points along the preset sequence direction of the starting pointas a preset end point, and if the gray value of the predetermined end point is equal to the second preset threshold value, performing a rectangular connection test; if the rectangular connectivity test passes, the range of the rectangular cutting area being determined, and the corresponding character being cut. As the cutting method is adopted, even image text with disordered position and multiple lines of content and different sizes can be flexibly and effectively cut quickly and accurately, and a large number of repetitive search and positioning processes can be effectively reduced, and therectangular range can be quickly determined and the cutting can be carried out.

Description

technical field [0001] The invention relates to the field of image and character recognition, in particular to an image and character recognition cutting method and a storage device. Background technique [0002] Optical character recognition (Optical Character Recognition) is the use of electronic equipment and detection to identify printed characters. With the automation and intelligence of social production and life getting higher and higher, OCR is used more and more widely, such as printing detection systems on various packages, license plate positioning and character recognition systems in intelligent transportation, and serial numbers in banknote recognition. Identification, serial number identification in bill identification, layout analysis, etc. Therefore, the development of high-efficiency optical character recognition system has great social and economic benefits. [0003] Therefore, how to perform character recognition and cutting efficiently and accurately is...
