matlab 实现人脸识别
人脸识别GUI设计
这是我在理解PCA算法后，设计`MATLAB GUI`实现人脸识别。
### 使用方法：
1. 运行face.m主脚本
2. 点击`训练机器`选择train文件夹
3. 点击`choose photo`选择test文件夹下的一张图片
4. 最后点击`recognize`即可进行识别
5. 点击`Accuracy`可计算整个test文件夹下所有图识别准确率
### 效果如下：

条形码识别
条码识别，MATLAB7.0下运行，仅支持一维条码[1] 剪切图像，并作旋转一定的角度。(2007-11-1，9:42)；[2] 剪切出第一个条形块。 (2007-11-2)；[3] 测试左斜的条形码，得出来的数据基本正确。(2007-11-2)[4] 采用两种方式对条形码进行锐化，一种噪声比较大，另一种噪声比较小；[5] 重新设计算法，先是进行边缘检测，提取条形码区域；然后对条形码区域进行锐化、光滑等预处理，再做识别；经过比较，采用prewitt边缘检测方法比较好。[6] 对12张图进行剪切，对剪切函数不断的修改！(2007-11-08)[7] 完成条形码区域的提炼，比较拉普拉斯和直方图均匀化增强方法，发现直方图均匀化效果比较好！(2007-11-09)[8] 比较矩不变量和大津二值化算法，大津算法效果比较好！->改进小区域剪切方法，先剪切上下后剪切左右！->增加二次剪切，解决旋转后造成的冗余量。(2007-11-09)[9] 调节pixelV门槛值，以及改正imagefilter函数；修改剪切函数，测试33张图片，除了w1/w2/w5/w25/w40/w41/w42因亮度不均、w39_w有些模糊等8张图片不能正确剪切出条形码外(同时说明大津算法值得改进)，其余的可以正确剪切出条形码，以待进一步处理和识别。2007_11_10[10] 字符能够识别，但是12个数据会有个把数据是错误的；主要是前面的预处理没有处理好，
