自己编写的BPSK调制与解调，内含matlab-figure-file、matlab-M-file和得出的jpg格式图形！(I have written BPSK modulation and demodulation, containing matlab-figure-file, matlab-M-file and come to the jpg format graphics!)

基于LBP的图像特征提取算法,检索效果大家可是自己实现试试，这种算法还是比较有优势的，但还需要很多改进(image retrieval algorithm based on LBP)

适合使用NUVOTON nuc501 做开发的参考。(The NUC501 is an ARM7TDMI-based MCU, specifically designed to offer low-cost and high-performance for various applications, like interactive toys, edutainment robots, and home appliances. It integrates the 32-bit RISC CPU with 32KB high-speed SRAM, crypo engine with OTP key, boot ROM, LDO regulator, ADC, DAC, I2C, SPI, USB2.0 FS Device, & GPIO into a cost-affordable whil feature-rich micro-controller.)

利用DFT变换实现数字水印的源代码，请大家赐教··(the code about the digital watermark in the region of DFT，using matalab)

说明：  这是一个在matlab中调用bioperl函数的算法示例(This is a matlab function to call the algorithm bioperl sample)
