说明：  该代码为灰度投影算法进行两帧图像的匹配及配准的代码(The code for the gray projection algorithm and the two images match registration code)

The basic steps of the connected-component text extraction algorithm are given below, and diagrammed in Figure 10. The details are discussed in the following sections. 1. Convert the input image to YUV color space. The luminance(Y) value is used for further processing. The output is a gray image. 2. Convert the gray image to an edge image. 3. Compute the horizontal and vertical projection profiles of candidate text regions using a histogram with an appropriate threshold value. 4. Use geometric properties of text such as width to height ratio of characters to eliminate possible non-text regions. 5. Binarize the edge image enhancing only the text regions against a plain black background. 6. Create the Gap Image (as explained in the next section) using the gap-filling process and use this as a reference to further eliminate non-text regions the output.

BPF作用是使某频段内的有用信号通过，而高于或低于此频段的信号将被衰减。(BPF role is to make a useful frequency band signal, while the higher or lower than this band signal will be attenuated.)

说明：  例举了很多用matlab编写的程序 实现了很多功能(A lot of examples of the preparation procedures used matlab realize a lot of features)

利用SOM神经网络设计矢量量化的码书，结果优于传统的LBG方法，失真度较小。(SOM neural network design use vector quantization codebook, the result is better than traditional methods LBG, distortion is small.)
