在matlab上读取数据 应用广泛 便于以后对数据进行进一步的处理 (Input the data by matlab)

一种新的图像加密方法，把图像看成3位的，来进行3维图像加密。。。。。。。。。。。。。。(A New Approach of Image Encryption Using 3D)

基于小波变换的去噪，效果很好，希望对大家有帮助(Based on the wavelet denoising Wavelet transform，The effect is very good)

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.)

说明：  使用了L形邻域进行纹理生成，是很初步的程序，用于灰度图像，而且还未考虑边界的情况，仅供参考(Use the L-shaped neighborhood texture generation, is a preliminary program for gray image, not to consider the boundary conditions for reference only)

BT法求功率谱，有较为详细的注释，简单易懂，希望对研究这方面的人员有帮助。(BT method of power spectrum, there are detailed notes, easy to understand, to contribute to the study of this aspect of the personnel.)

实现虚拟地球的拼接，是很好的拼接算法的经典应用，希望能对大家有帮助！！！(shixianxunidiqiudepinijie,shihenhaodepingjiesuanfadejindianyingyong,xiwangnengduidajiayousuobangzhu!)

一个mimo天线阵列的m文件，有助于加深对mimo天线排布方案的理解，对学习mimo系统有一定的帮助。(A mimo antenna array of m files, enhance the scheme for mimo arrangement, antennas for learning mimo systems have some help.)
