说明：  考虑DCT阈中量化效应，采用8X8的DCT模板，选择量化步长，结合缩放因子进行图像压缩。(Considering the quantization effect in DCT threshold, we use the 8X8 DCT template, select the quantization step, and combine the scaling factor to compress the image.)

说明：  图像重建Matlab程序，仅供参考学习，希望对您有用。大家一起学习进步。(Image reconstruction matlab program, only for reference learning, hope to be useful to you. Let's learn and improve together.)

采用FDTD时域有限差分法计算电磁波的传播问题等,(The finite difference time-domain (FDTD) method is used to calculate the propagation of electromagnetic wave.)

基于小波的人脸识别算法的matlab实现(Face recognition based on wavelet algorithm to achieve the Matlab)

改进分水岭算法，详细注解标在m文件内了，希望对大家有用(Improved watershed algorithm and hope for all of us)

平台基于visual studio2015，使用opencv函数实现高斯滤波，进行图像处理(gaussian blur based on opencv)

能够实现对高光谱数据影像的平滑，可以根据需要设置平滑参数并且能够批量处理(Hyperspectral Smooth)

说明：  图像几何变换（如旋转）时用到的最近领域和双线性插值方法，(Image geometric transformations (eg rotation), when used in recent field and bilinear interpolation methods,)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

这种方法可以用来实现对SAR图像的多普勒中心进行估计(This method can be used to realize on the SAR images to estimate the Doppler centroid)
