If I has more than two dimensions, then the image is treated as a multidimensional grayscale image and not as an RGB image.. imnoise expects pixel values of data type double and single to be in the range [0, 1]. For example, to draw a square, you simply provide the x- and y-axis coordinate for each corner. Color pictures generally contain three times as much data as grayscale pictures, depending on what color representation scheme is used.
