The camera identifies the phone number in the picture.

Use the Open Source feature library (need to be stored in the phone's SD card root directory); Get a picture of a scanned phone number box in the camera preview bitmap object, to the open source code identification number, the recognition of the number of digits into the mobile phone number of the regular expression matching

In the process of identifying the mobile phone number, in order to increase the recognition rate: you can refer to the article has: http://www.oschina.net/code/snippet_1422728_34167 landlord using C language written

But after the idea, you can refer to the numbers and letters in the image. BOBO2CJ posted on March 17, 2014 15 o'clock, 13 reviews/16261 read a picture recognition gadget, Originally mainly to identify the previous company's software registration code in the numbers and letters (each time a box to copy out paste into the registrar, very troublesome!). ), because the registration code appears in the letters and numbers are basically the few, so the scope of the recognition library is set to a relatively small.
The principles and algorithms are explained in detail in the code, the function has a great limitation, but my idea is to share this idea and the way to realize it.
