gray_imread

Read any image as grayscale

im = gray_imread(filename)

This is a simple utility routine to read any image as grayscale. If the image is truecolor or pseudo-color, it is converted using im2gray

initial_dir = PWD;
chdir (SIPDIR + 'images');

Img = gray_imread('ararauna.png');
clf
imshow(Img,[]);

chdir(initial_dir);
