Abstract
Provided is an algorithm of verification code recognition. According to a double-acceleration mechanism, the recognition speed of verification codes is effectively increased, and balance between the recognition speed and recognition accuracy is achieved.
Description
Technical field
Along with the high speed development of the Internet, network brings greatly easily simultaneously in the life of giving people, and its safety problem also becomes increasingly conspicuous.Network verification code, as widely used checking means, plays an important role to network security.
Background technology
Identifying code concept is along with the fast-developing of Internet technology and application, and network is providing affluent resources and while greatly easily to people, and incident is exactly the safety issue of internet system.The product of web system safety is strengthened in the appearance of identifying code just.This is identifying code the most frequently used in network for picture validation code based on character.It easily produces, and has model answer, is not subject to the impact of background knowledge and cultural difference, and Brute Force complexity is very large, and nearly all website in the country and most external website are all to adopt this kind of identifying code.
Summary of the invention
By national patent, retrieve and there is no to find the application materials about this system aspects.
Exclusive overall recognition mode, image, without cutting apart, does not even need noise reduction to identify, for noise spot, that interfering line cannot be removed clean image is effective especially.
1, three cut apart greatly pattern: auto Segmentation, on average cut apart, vertical segmentation, image is cut apart lighter.
2, the ten large filters of processing: exceed the graphics process filter of 33 kinds, all write voluntarily bottom code, more complicated identifying code also can effectively process, obtain rapidly salubrious binary image, process identifying code figure easier.
3, powerful type matrix is made and administration interface: greatly save and make the type matrix time, input after the character that type matrix is corresponding, can disposablely obtain tens even hundreds of type matrixes.
4, advanced identification speed technology: dual acceleration mechanism, effectively promote identifying code recognition speed, reached recognition speed and accuracy balance.
Claims (1)
1. the algorithm of an identifying code identification is characterized in that: cut apart identification, mixing identification, entirety identification, identification fast, effectively identification character distortion, adhesion or overlapping identifying code.
