基于对话框创建浮动工具栏

利用LZW的压缩算法实现文件的压缩与解压缩。用c++和MFC实现，代码简洁，实现简单，可用(LZW compression algorithm using the file compression and decompression.)

SST25VF016B可以做为AT45DB161的替代品，而且价格低廉。(SST25VF016B AT45DB161 can be used as a substitute, and low prices. Is the ideal alternative.)

stm32处理器，adc后采集的温度数据经dma读取，串口显示，systick时钟延迟，lcd显示温度数据！(stm32 processor ，temperature data collected in the adc which is read by dma serial and display by systick clock delay, lcd display temperature data)

在图像的DCT系数上嵌入信息，图像为常见的512*512大小的灰度图（实验所用图像为LENA.BMP）。嵌入的信息为一二进制Logo图（实验所用logo图为tj-logo.bmp），该图大小为32*32，共1024个Bit。 1. 在LENA图中嵌入水印，输出嵌入后的水印图像。 2. 对水印图像解码，输出解码后得到的logo图，并统计错误率。 3. 使用不同的嵌入强度进行嵌入，观察其对作品直觉效果和解码效果的影响，绘制相应的曲线。 4. 使用加入噪声、改变对比度、JPEG压缩等攻击方法对水印作品进行攻击，查看解码的效果。 (Information embedded in the DCT coefficients of the image, the image of the common 512* 512 size gray-scale (experimental image LENA.BMP). Information embedded in a binary Logo Figure (used in the experiment logo picture shows the tj-logo.bmp), the plot size 32* 32, 1024 Bit. LENA Figure embedded watermark, the watermark image output embedded. (2) logo watermark image decoding, the output decoded Figure statistical error rate. (3) using a different embedding strength for embedding, observe the works intuitive effects and decoding results, and draw the corresponding curve. (4) by adding the noise, change the contrast, JPEG compression attack methods to attack, to see the effect of decoding the watermark works.)

说明：  周立功公司的P89V51RD2的IAP升级实现的，完整文档，官网只能载到前三章。(Ligong P89V51RD2 week' s escalation of the realization of the IAP, complete documents, the official website only contains three chapters.)

基于opencv的行人检测，用到了svm,haar特征等等(Opencv-based pedestrian detection, use the svm, haar features, etc.)
