为了研究植物的生长规律，应用数字摄影图像处理法对山楂叶面积进行无损测量，该方法采用数码相机在田间获取山楂叶子的数字图像，对所拍图像进行背景去除、二值化及中值滤波处理，然后利用Matlab软件编程．快速计算出叶子的面积。把这一面积同常用的叶纸称重法所测面积进行比较．结果基本相同，由此可见，数字摄影图像法测量叶面积，具有简单、准确、方便快捷的特点．这对数字农业的植物信息快速采集和利用具有重要的意义。 ( In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of hawthorn leaves in the field, on the film image background removal, binarization and medianfiltered, and then using the Matlab software programming. Quickly calculate the area of the leaves. This area with the common leaf paper weighing measured by the area to compare. The results are basically the same, shows, digital photographic images method to measure leaf area, with a simple, accurate, and convenient features. This rapid acquisition and use of digital agricultural plant is of great significance. In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of )

说明：  Calculate the Laplacian of an image, can be accelerated by the GPU.

两船协同导航，利用EKF滤波，主要用于主从式的协同导航，滤波参数要根据实际需要合理调节(Collaborative navigation of both vessels, the use of the EKF filter, mainly used for the master-slave collaboration navigation filter parameters according to the actual needs of a reasonable adjustment)

按照夹角余弦距离计算待测样品与样品库的样品相似度(Cosine distance calculation in accordance with the test sample and the sample database sample similarity)

关于分水岭图像分割的源码，需要的可以下来用(watershed image segmentation on the source need to be down with the)

C#写的绘图板，功能还不错。实现了直线，矩形，圆形，填充矩形，填充圆形。可拖动图形位置，可改变矩形大小，可放大缩小，可输入文字，打开图片，拖动图片，可撤销。(C# to write the drawing board, features well. Implementation of linear, rectangular, circular, filled rectangle, filled circle. Can drag the graphic location, can change the rectangle size can be enlarged or reduced, can enter text, open the image, drag the image may be revoked.)

运动目标检测与跟踪，包括目标定位，匹配与跟踪!(moving target detection and tracking, including Target, matching and tracking!)

相机标定工具箱，首先通过线性的方法求解出部分的摄像机参数，然后再利用非线性优化方法求出包括畸变系数在内的所有标定参数的最优解(Camera Calibration Toolbox for Matlab)

图像拼接 sift 特征点，两幅图像进行拼配 拼接，先找找出特征点匹配(The image stitching， sift feature points, two images blending splicing find someone to identify the characteristics of point matching)

图像的平滑函数，对指定区域的图像，并有门限值和魔板大小限制。(the smooth of a bmp image)
