Example Embodiment

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings.

[0034] The existing OCR technology uses computers to recognize images. Due to the characteristics of the computer itself, its correct recognition rate is not high; but the human eye can recognize text features that OCR technology cannot correctly recognize, especially in verification code verification. In the process. The present invention includes the image to be recognized in the verification code picture, and human eyes recognize the text feature in the image to be recognized, so as to realize the extraction of the text feature in the image to be recognized, thus improving the correct recognition rate of the text feature.

[0035] The following first describes the existing verification code verification method. The verification code is a type of challenge-respons...

Abstract

The invention discloses a method for test recognition based on verification and a device thereof, the steps of the method comprise receiving a verification request, splicing a generated identifying code segment and a to-be-recognized image segment comprising test characteristics into an identifying code image to transmit to a terminal, receiving user recognition information which is transmitted by the terminal and is input by users after the users recognize the identifying code image, and extracting text characteristics included by the image segment in the user recognition information to be the recognition result of the image segment. The scheme of the invention increases the accurate recognition rate of the recognition result, and resolves the limitation of the computer recognition.

Description

technical field [0001] The invention relates to image recognition technology, in particular to a verification-based text recognition method and device. Background technique [0002] Image recognition technology includes recognizing text features in images. Here, the recognition of text features in images is called text recognition. Text features include characters, numbers, and symbols. At present, text recognition is often carried out by computer, among which optical character recognition (OCR, Optical Character Recognition) method is often used, and OCR method belongs to pattern recognition (PR, Pattern Recognition) technology. [0003] see figure 1 , which is a flowchart of the OCR method in the prior art, the method includes the following steps: [0004] Step 101, image input. [0005] Scan text images such as printed products containing text features through a scanner, and input the scanned images into a computer. [0006] In step 102, the computer performs image pr...
