Imageprocessing

DCT变换的MATLAB代码。无私奉献啦。希望给有用的朋友(DCT Transform MATLAB code. Selfless dedication啦. Want to give useful Friend)

典型的一维kalman滤波原理程序，容易掌握！(typical one-dimensional Kalman filtering process easy!)

很有用的gdal库，并且已经编译好。请多多指教!(It is a very good resource！Please download！！)

对图像进行平滑处理，像各种滤波的方法，如均值滤波法、中值滤波法(Smoothing the image, like the various filtering methods, such as mean filtering, median filtering method)

裁剪以RGB565格式保存的BMP文件，涉及位图掩码内容(imagecut of the BMP picture which saved with RGB565 format and mask)

测地线GAC模型可以分割灰度图像，分割效果良好(Geodesic active contour)

对叶片进行预处理和提取部分特征：1.均值去噪 2.k均值聚类提取复杂背景下的叶子图片 3.填充孔洞 4.去叶柄 5.提取轮廓 6计算纵横轴比、面积凹凸比、周长凹凸比、球形性、圆形性、偏心率、形状参数和矩形度等特征值并进行画图。( Pretreatment of leaves and extract some of the characteristics: a mean denoising 2.k means clustering leaf extract complex background picture fill holes 3 4 5 contour extraction petiole 6 to calculate the vertical and horizontal axis ratio, convex area ratio.. convex perimeter than spherical, circularity, eccentricity, and rectangular shape parameter values ​ ​ and other characteristics of the drawing.)

读取图片，用鼠标获取图片点坐标，输出坐标数据(Read the image, the image point coordinates obtained with the mouse, and output coordinate data)

这是一个简单的区域生长算法，方便新手学习使用。(this is a simple region growing algorithm available for new learners.)

将某一8位的raw格式图转换为16位的raw格式图 并可输出raw格式图的灰度值至相应文件（.txt文件） 生成的新图用PS打开时与原图基本一致.(It can converted an 8-bit raw format, to an 16-bit raw format and can output raw format diagram of the gray value to the corresponding map file (. Txt files) .The new plan to open with PS are basically consistent with the Original.)
