12.1 read and show an image Read an image:imread() Show an image:imshow() 示例: 图12-1 imread and imshow函数 图12-2 image matrix函数 其实一张图片有rgb三种颜色,每个点就是一个矩阵的数值,而这个数值就代表着rgb,所以我们操作以一个图片,也就相当于操作一个矩阵内的数值,或者说,修
Image Matrix:291x240的矩阵。 图像信息: imageinfo() imageinfo('pout.tif'); Image Viewer imtool() 得到image viewer中的像素信息 >> imtool('pout.tif'); 图像处理 信号处理的一种形式,输入是一张图像 noisy -> gaussian -> median -> wiener 图像四则运算 图像数乘 使得图像亮度变大变小: I = ...
数组存储ROB 图像的例子。 3、索引图像(indexed Image) 索引图像往往包含两个数组,一个图像数据矩阵(Image Matrix )和一个颜色索引表( Colormap )。对应于图像中的每一个像素, 图像数据数组都包含一个指向颜色索引表的索 引值。 颜色索引表是一个m× 3 的双精度型矩阵, 每一行指定一种颜色的 3 个 RGB 分...

首先，MATLAB中image和imshow都可以用来图像显示，image函数的语法调用常有以下几种格式：image（A）；image（x,y,A）;其中，image（A）是将矩阵A 作为一个图像显示，A中的每一个元素都被指定一种颜色；image（x,y,A）其中的x,y分别表示显示图像左上角的坐标，其它与image（A）含义相同。当然image...
2.2.1. Image input and output Just as any other data set in MATLAB, images are represented by a variable. If we consider an image file with name ‘image’ and format ‘tiff’, using the function imread, the image can be loaded as a 2D or 3D matrix, depending on the image type. Im...
