Rgb To Grayscale Matlab. The im2gray function accepts grayscale images as inputs and returns them unmodified. I rgb2gray rgb converts the truecolor image rgbto the grayscale intensity image i.
The im2gray function accepts grayscale images as inputs and returns them unmodified. I im2gray rgb converts the specified truecolor image rgb to a grayscale intensity image i. The rgb2gray function converts rgb images to grayscale by eliminating the hue and saturation information while retaining the luminance.
In the case above each of the red channel green channel and blue channel are all the same so the the image will appear gray scale as i said in the comment above that line.
