What is the difference between 1 dimensional, 2 dimensional and 3 dimensional image? please give it with example

I need to interprate the image dimensions for understanding the scale space of images. please give the difference between 1D, 2D and 3D images.

A 1D image is just a line, like you extract a single line out of a 2D gray scale image. A 2D image can be a grayscale or color image in layman's parlance, though in MATLAB, a 2D color image is actually a 3D image because it has 3 2D images - one for each color plane. A 3D image can be a color image, like I just said, or it can be a hyper spectral image, like for satellite/remote sensing, where you have 7 or more wavelength bands that the sensor collected. A 3D image may also be a grayscale volumetric image, like from MRI or CT. So it's a mapping of what's inside a volume and gives the density, activity, temperature, brightness, concentration, or whatever you're measuring, at each x,y,z location in a 3D rectangular volume/box.

Is that what you meant by "interprate"?
