In MATLAB, distinguishing between two-dimensional (2D) and three-dimensional (3D) images can be done by examining the size of the image array.
dims = size(img);
Use the size function to get the dimensions of the image array. This function returns an array where each element represents the size of the image in a specific dimension.
- A 2D image typically has the dimensions [height, width].
- A 3D image (such as a color image) usually has the dimensions [height, width, channels], where channels is often 3 for RGB images.
