1. 基本操作 读取图像imread() 展示图像imshow() clear, close all I = imread('pout.tif');%read,这幅图的命名为‘pout.tif’imshow(I);%show pout.tif 为MATLAB自带图像,无需手动添加 获得图像信息imageinfo() 获得图像像素信息imtool() 2. matlab 内建图像算法 3. 图像相乘、相加 图像相乘immultiply(...
把图像二值化(将米粒变成白色,背景变成黑色) 计算连接的白色像素点 2. 图像阈值化 (Image Thresholding) 计算图像理想的阈值等级:graythresh() 将图像转换为二值图像:imbw() I = imread('rice.png'); level=graythresh(I); bw=im2bw(I, level); subplot(1,2,1); imshow(I); subplot (1,2,2); imsh...

MATLAB provides interactive apps and built-in functions that help you automate 3D image segmentation routines. Thisexampleshows how to perform a 3D segmentation using active contours (snakes). Interactively segment 2D slices of the volume using theImage Segmenter appto create a starting point for the...
