Example:a truck violated the traffic rules and ran away after hitting people. Three people witnessed the scene, but did not remember the car number, only to note some of the characteristics of the car number. A said: The first two digits of the licence are the same; B said: The last two digits of the licence are the same, but different from the first two; C is a mathematician, he said: The four-bit car number is exactly the square of an integer. Please ask for the car number according to the abo
A said the first two bit likewise, B said after the two same, C said the four-digit license plate number is just a number of square. What's the license plate number?Using System;namespace consoleapplication1{ class program { static void Main (string[] args) { int k, C; for (int

In order to use depth learning to train a character recognition model for license plate recognition, the first problem to be solved is to deal with the data problem, in order to be able to pass the data into the network for training, I use the One_hot code, the specific details are as follows:
First prepare the DataSet: part of your own dataset, part of the EASYPR dataset (the latter 500 images as test sets
The realization of OPENCV's CVSVM is based on LIBSVM,LIBSVM, a world-famous SVM library written by Professor Lin Chih-jen of Taiwan University (probably the most widely used library in the industry today). The input of SVM's Perdict method is the characteristic of the data to be predicted, also called features. Here, we enter a feature that is all pixels of the image. Since SVM requires that the input should be a vector, and mat is a matrix corresponding to the width of the image, we need to use
