于傅里叶变换的图像加密技术研究 具体是将一幅图像用 fft 变换到频域 在频域中进行加密 我考虑的是通过随机相位来加密的方法，请问用matlab怎样实现 加密后在通过 ifft 得到加密后的图象 -Fourier transform in the image encryption technology to study the details of an image is to use fft transformed to the frequency domain in the frequency domain I consider encryption is through random-phase approach to encryption, Will the use of Matlab how to achieve the adoption of encryption ifft be encrypted images

高斯滤波核函数生成,可以根据K和要生成对应的高斯核-Gaussian filter kernel generation, according to K and to generate the corresponding Gaussian kernel

bandelet 去噪，包含blsgsm和平移不变去噪，不过对大图像需要的内存比较大-bandelet denoising, including blsgsm and translation invariant denoising, but for large images need more memory

自动搜索最佳阈值，对图像进行二值化处理，提取边缘-Automatically search the best threshold image binarization processing, extraction of the edge

otsu算法实现，可以自适应获取阈值，对图像进行二值化。里面配有图像均衡化的程序一起使用，效果更好-otsu algorithm, you can get adaptive threshold for image binarization. Which is equipped with image-based program used in conjunction with a balanced, better

对比拉伸好的c++程序，希望对美国那边的图像处理有帮助

用于实现相机的自动调焦，里面又自己定义的调焦函数，利用清晰度评价的方法去调焦。用于实际的工程运用。-Used to implement auto-focus camera, which has its own definition of focusing function, the use of evaluation methods to focusing clarity. Used in actual engineering applications.

这是一个图像的预处理程序，把几个图像进行平均-This is an image preprocessing procedures, the average number of images

The source is to detect motion objects with building models in backround of the image,very useful in image processing.

rice大学CHOI写的一个关于小波域HMT模型的图像去噪算法。算法比较经典。对研究HMT模型的同行有很大参考价值。-rice university CHOI written on wavelet-domain HMT model for image denoising algorithm. Comparison of the classical algorithm. HMT model of research has great reference value counterparts.
