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.

实现QPSK调制，映射成星座图上对应的复数点；将星座图上的复数点作QPSK解调。 16和64位QAM调制。(The QPSK modulation is mapped into the corresponding complex points on the constellation diagram, and the complex points on the constellation diagram are demodulated by QPSK. 16 bit and 64 bit QAM modulation.)

很不错的程序，里面有详细的注解说明，可以拿来借鉴一下(very good procedure, there are detailed explanatory comments can be used to learn some lessons from)
