matlab开发的一些关于基于GVF的图像分割算法，(matlab developed some of the GVF-based image segmentation algorithm,)

图像变换检测 主成分分析法 含PDF介绍(iamge change detection using PCA)

说明：  图像去噪，梯度倒数加权滤波代码噪matlab中实现(Image denoising, countdown weighted gradient noise filtering matlab code to achieve)

将一幅rgb图像转换成灰度图像，并显示出灰度图像。(the functon is to make a rgb image to gray image.)

说明：  研究生期间做的unscented kalman 滤波程序，带测试例子，vc6编译(Graduate students during the unscented kalman filtering process, with the test example, vc6 compiler)

改进SIFT算法，用于光学图像和SAR图像配准(Improved SIFT methods for Registration of Optical and SAR image.)

使用IDL实现对ENVI所支持的影像文件格式的数据拼接，不用打开栅格，从而避免内存消耗过大(IDL data stitching ENVI image file formats supported, do not open the grid, in order to avoid memory consumption is too large)

说明：  对线激光相机标定，使用matlab编程，里面带有数据集，写好的函数。(Calibration of line laser camera, programming with MATLAB)

分别利用均值滤波、自适应滤波和中值滤波对噪声图像g1和g2进行滤波，利用峰值信噪比对去噪性能进行比较。(Respectively, using the mean filter, adaptive filtering and median filtering images g1 and g2 noise filtering, denoising performance comparison using the peak signal-to-noise ratio.)

There is a BCB program for digital image to establish ground truth image which test the original image.
