基于MSP430F149单片机UART驱动程序(UART driver based on MSP430F149 MCU)

这两天在网上看到一张让人涨姿势的图片，图片中展示的是贪吃蛇游戏， 估计大部分人都玩过。但如果仅仅是贪吃蛇游戏，那么它就没有什么让人涨姿势的地方了。 问题的关键在于，图片中的贪吃蛇真的很贪吃XD，它把矩形中出现的食物吃了个遍， 然后华丽丽地把整个矩形填满，真心是看得赏心悦目。作为一个CSer， 第一个想到的是，这东西是写程序实现的(因为，一般人干不出这事。 果断是要让程序来干的)第二个想到的是，写程序该如何实现，该用什么算法？ 既然开始想了，就开始做。因为Talk is cheap，要show me the code才行。 

打印“魔方阵”。所谓“魔方阵”是指这样的方阵，它的每一行、每一列和对角线之和均相等。例如，三阶魔方阵为: 8 1 6 3 5 7 4 9 2 要求打印出由1到n*n的自然数构成的魔方阵。-Print "magic matrices." The so-called "magic matrix" refers to the matrix, which each line, each diagonal out and the sum of all the same. For example, third-order magic Lineup : 8 1 6 3 5 7 4 9 2 request from a print n* n to the natural form of the magic number of matrices.

很好的模拟器源代码！-good simulator source code!

用meanshift算法实现图像的平滑和分割的算法(Algorithm used meanshift image smoothing and segmentation algorithms)

闻亭公司视频通信模块（VCM_DM642）技术参考资料,版本号：V1.0.详细介绍了这块板子的硬件配置情况,对入门很有帮助.-Wintech Video Communication Module (VCM_DM642) Technical Reference, version: V1.0. Detailed information on the hardware configuration of this board, the on entry helpful.

帧间差分法是一种通过对视频图像序列中相邻两帧作差分运算来获得运动目标轮廓的方法，它可以很好地适用于存在多个运动目标和摄像机移动的情况。当监控场景中出现异常物体运动时，帧与帧之间会出现较为明显的差别，两帧相减，得到两帧图像亮度差的绝对值，判断它是否大于阈值来分析视频或图像序列的运动特性，确定图像序列中有无物体运动。图像序列逐帧的差分，相当于对图像序列进行了时域下的高通滤波。实例中有对应avi文件(Inter-frame difference method is a method that obtains the contour of moving object by differential operation of two adjacent frames in video image sequence. It can be well applied to the situation where there are multiple moving objects and camera moving. When abnormal object motion occurs in the monitoring scene, there will be obvious difference between the frame and the frame. By subtracting the two frames, the absolute value of the brightness difference between the two frames can be obtained. The motion characteristics of video or image sequence can be analyzed by judging whether it is larger than the threshold value, and whether there is object motion in the image sequence can be determined. The frame-by-frame difference of image sequence is equivalent to high-pass filtering of image sequence in time domain. There are corresponding avi files in the instance)

说明：  使用美国辛辛那提大学的数据，进行小波，时域，时频域提取特征，使用马氏距离对其进行性能退化。(Using data from the University of Cincinnati in the United States, wavelet, time domain, time-frequency domain features were extracted, and markov distance was used to degrade its performance.)

说明：  这是DB2错误码，在SQL语句使用中会出现错误，就可以查找这些错误码及时解决问题(This is the DB2 error code. If there are errors in the use of SQL statements, you can find these error codes and solve the problem in time.)
