实验一图像一的细胞计数 一、实验内容及步骤 将该图形进行一系列处理，计算得到途中清晰可见细胞的个数。 首先，由于原图为RGB三色图像处理起来较为麻烦，所以转为灰度图，再进行二值化化为黑白图像，得到二值化图像之后进行中值滤波得到细胞分布的初步图像，为了方便计数对图像取反，这时进行一次计数，发现得到的个数远远多于实际个数，这时在进行一次中值滤波，去掉一些不清晰的像素点，剩下的应该为较为清晰的细胞个数，再次计数得到大致结果。 二、Matlab程序代码 clear;close all; Image = imread('1.jpg'); figure,imshow(Image),title('原图'); Image=rgb2gray(Image); figure,imshow(Image),title('灰度图'); Theshold = graythresh(Image); Image_BW = im2bw(Image,Theshold); Reverse_Image_BW22=~Image_BW; figure,imshow(Image_BW),title('二值化图像'); Image_BW_medfilt= medfilt2(Image_BW,[3 3]); figure,imshow(Image_BW_medfilt),title('中值滤波后的二值化图像'); Reverse_Image_BW = ~Image_BW_medfilt; figure,imshow(Reverse_Image_BW),title('图象取反'); Image_BW_medfilt2= medfilt2(Reverse_Image_BW,[20 20]); figure,imshow(Image_BW_medfilt2),title('第二次中值滤波的二值化图像'); [Label, Number]=bwlabel(Image_BW_medfilt,8);Number [Label, Number]=bwlabel(Image_BW_medfilt2,8);Number

数字图像去噪典型算法及matlab实现 希望得到大家的指点和帮助 图像去噪是数字图像处理中的重要环节和步骤。去噪效果的好坏直接影响 到后续的图像处理工作如图像分割、边缘检测等。图像信号在产生、传输过程中都可能会受到噪声的污染，一般数字图像系统中的常见噪声主要有：高斯噪声（主要由阻性元器件内部产生）、椒盐噪声（主要是图像切割引起的黑图像上的白点噪声或光电转换过程中产生的泊松噪声）等； 目前比较经典的图像去噪算法主要有以下三种： 均值滤波算法：也称线性滤波，主要思想为邻域平均法，即用几个像素灰度 的平均值来代替每个像素的灰度。有效抑制加性噪声，但容易引起图像模糊， 可以对其进行改进，主要避开对景物边缘的平滑处理。 中值滤波：基于排序统计理论的一种能有效抑制噪声的非线性平滑滤波信号处理技术。中值滤波的特点即是首先确定一个以某个像素为中心点的邻域，一般为方形邻域，也可以为圆形、十字形等等，然后将邻域中各像素的灰度值排序，取其中间值作为中心像素灰度的新值，这里领域被称为窗口，当窗口移动时，利用中值滤波可以对图像进行平滑处理。其算法简单，时间复杂度低，但其对点、线和尖顶多的图像不宜采用中值滤波。很容易自适应化。 Wiener维纳滤波：使原始图像和其恢复图像之间的均方误差最小的复原方法，是一种自适应滤波器，根据局部方差来调整滤波器效果。对于去除高斯噪声效果明显。 实验一：均值滤波对高斯噪声的效果 l=imread（'C:\Documents and 桌面\1.gif'）;% 读取图像
