采用8个阵元，利用CAPON算法，进行DOA，画出波达方向估计误差随着信噪比变化的曲线图(Eight elements, the use of the CAPON algorithm of DOA draw the DOA estimation error changes with the SNR curve)

利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)

de-speckling of noise in medical ultra sound images...

利用otsu算法实现图片的自动多阈值分割；用matlab编写的自动多阈值分割程序，分割图像之前采用自动平滑图像(Using otsu algorithm to realize multi- threshold segmentation of pictures)

说明：  包括canny，sobel，log等边缘检测的改进算法，使用效果良好(Including improved edge detection algorithms such as canny, sobel, log and so on, the application effect is good.)

说明：  用于医学图像融合CT和MRI灰度图像，MRI和PET的彩色图像融合(For medical image fusion)

Tarel和Hautiere的图像去雾方面的程序，去雾效果很不错，对于研究很在参考价值。(Tarel and Hautiere image to the fog of program, go to mist effect very good, to study in a reference value. )

这是基于张亶，陈刚《偏微分方程的图像处理》书的实验及程序(image processing )

利用非线性结构张量处理一些图形问题，能够有效的解决和优化现成的处理方法(In this article, we introduce nonlinear versions of the popular structure tensor, also known as second moment matrix. These nonlinear structure tensors replace the Gaussian smoothing of the classical structure tensor by discontinuity-preserving nonlinear diffusions)

给定一幅图像，输出其直方图。给定一个线性变换函数(可以输入不同的参数)，实现图像的灰度拉伸；实现对图像的均衡化。 实验测试图像：任意 (histogram；Gray stretch；Image equalization)
