Opencv achieves character segmentation for License Plate Recognition, opencv license plateIntroduction
In the previous article, we have located the license plate number in the image, copied the license
[Code Note] verifies the mobile phone number, email address, license plate number, and license plate number.
I. Code.
-(Void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view. NSLog (@ "------ % d ------", [self isValidateEmail: @ "12345"]); NSLog (@ "------ % d ------", [self isValid
As mentioned in the previous article, license plate locating is based on an example in the opencv sample. I think it is theoretically feasible, but I have never performed any operations. Today I am free. I modified the code and tried several images. I found that the effect is good. The code is specially pasted to communicate with opencv learners and hope to give some guidance with high fingers. O (partition
/*** First: Ordinary cars* License plate number format: Kanji + A-z + 5 bit A-Z or 0-9 (license plate number does not exist letter I and O Prevent and 1, 0 confusion)* (only common license plate number, Coach car, police grade.) S

Auto license plate self-identification the whole process is divided into pretreatment, edge extraction, license plate location, character cutting, character recognition five modules, the character recognition process mainly consists of the following 3 part of the composition :① correctly cut the text image area;② the c
In this tutorial, I'll take you to use Python to develop a license plate recognition system using machine learning technology (License Plate recognition). What we're going to do.
The license plate recognition system uses optical
At present, the technology of license plate recognition is quite mature. In the last one months of study time, the entire license plate recognition process went through, there is a relatively clear, comprehensive understanding.

4.3 The improvement method in this paper
Through the introduction of the above two methods, it can be seen that the horizontal projection method for the only connected characters and no interference in the license plate has a good segmentation effect, and the complexity of the algorithm is relatively simple, but for the inclusion of non-connected or sticky characters in
License Plate positioning is the first and most important step in License Plate Recognition.
Due to the diversity and different colors of Chinese license plates, coupled with frequent damage to license plates, and too many interfe
