若遇到需要将图像从颜色格式转换为灰度格式的情况，两者操作方式有别。rgb2gray 函数专为此目的设计，而 im2gray 则不支持直接转换颜色图。对于颜色图的灰度转换，推荐使用 cmap2gray 函数。为深入了解 im2gray 函数的使用与特性，可直接在 MATLAB 命令行输入“doc im2gray”。通过此指令，可以获取关于该函数...
Matlab数字图像处理-im2gray与rgb2gray区别 无相破相 1 人赞同了该文章 im2gray 函数与 rgb2gray 基本相同,不同之处是它可以接受灰度图像作为输入并原样返回它们。 如果输入图像是灰度图像,则 rgb2gray 函数返回错误。如果使用 im2gray 函数,就不再需要类似如下的循环代码。 if ndims(I) == 3 I = rgb2gray(I);...
Open in MATLAB Online im2gray() was introduced in R2020b. You're using R2020a. Depending on what you need, you might be able to do it with rgb2gray() and some array size checks. switchsize(inpict,3) case3 outpict = rgb2gray(inpict); ...
