三边滤波器是在二边滤波器上做的改进，对图像处理有广泛的应用。(Trilateral filter is a filter on the two sides to make improvements on a wide range of image processing applications.)

用来将一个指纹图片切成指定像素大小的片段，并将计算他的方向场和系数(Used to cut a fingerprint image into the specified pixel size pieces, and calculates the direction of the field and the coefficient )

说明：  直接可以运行的，基于matlab平台，里面包含了frost滤波,Lee滤波和kuan滤波，均可以直接运行。(Can run directly, based on MATLAB platform)

说明：  一个基于matlab的改进的灰度图像分水岭分割算法，该算法改进了普通的分水岭算法的过分割等问题，经过一系列处理可是分割结果更加准确。(Matlab based on gray-scale image of the improved watershed segmentation algorithm to improve the ordinary over-segmentation of watershed algorithm and so on, but after a series dealing with a more accurate segmentation results.)

将RGB格式的图片进行mosaic处理得到RawData格式的图片，然后再恢复成RGB格式彩色图片,laroche-CFA插值算法(turn an RGB picture to RawData picture，then recover the RawData picture to an RGB picture.it is called laroche-CFA.)

运用GVF snake进行图像分割。效果好，可用于学习借鉴。(image segmentantion based on GVF snake.)

该上传的256张CT图片是高质量的DICOME格式人类头骨的连续序列切片图，可直接用于医学三维重建或体绘制。(The upload of 256 CT images are of high quality DICOME form a continuous sequence of the human skull slice diagram can be directly used in medical 3D reconstruction or volume rendering.)

在idl环境下批量处理提取modis ndvi数据(the program can extract the ndvi data from modis ndvi product)

PCA的matlab实现源码，初学者实用(Matlab realize the PCA source beginners practical)

实现人脸识别及分割，使用人脸进行RGB颜色提取，并分层提取特征信息。(Realize face recognition and segmentation, use face for RGB color extraction, and extract feature information hierarchically.)
