Digital image face detection had been developing so much in this last decade. The searching for the best
method is still walking until today. This face detection research is using color model based segmentation method
combined with template matching. There are 4 main process in this research. First, motion detection is used to
minimize the size of the image by subtracting image n with image n+m. Then, by using YCbCr color model based
segmentation, the image is separated by skin color area and non-skin color area. Third, is to reduce the noise by
using the blurring way and by filtering its wide. The last one is matching the area that last with template that has
been prepared to detect which area is face. The result of the research, from 217 images and 10 videos , shows
that this method reach up to 70,5 face detection accuration procentage.

Demo_CR95HF
在工作中曾完成的一个NFC读卡器，
主要使用的ST公司的新推出的CR95HF芯片，做板测试已OK。
对于从事NFC开发的人员绝对是一种值得备用的资料。
（附件提供原理图，CR95HF编程手册，驱动CR95HF的C源代码，另包含有 对双接口芯片M24LR64的驱动）
CR95HF芯片有如下特点：
标准频率：13.56-MHz
支持多协议：ISO/IEC 14443 A and B，ISO/IEC 15693，ISO/IEC 18092
提供2种标准接口： SPI 和 UART 。
只需简单的7条指令：
(Work was done in a NFC reader, the main use of the ST' s new CR95HF chip board test has to do OK. Personnel engaged in the development of NFC is definitely a worthy alternative information. (Annex provides schematics, CR95HF programming manual, driver CR95HF the C source code, and the other contains the dual interface chip M24LR64 driver) CR95HF chip has the following characteristics: standard frequency :13.56-MHz multi-protocol support: ISO/IEC 14443 A and B, ISO/IEC 15693, ISO/IEC 18092 provides two standard interfaces: SPI and UART. 7 simple instructions:)
