What do you mean by depth? Like bit depth, like 8 bits or 16 or 24 bits? Or depth like you have a topographic image?

You can use IMFINFO to find the bit depth of an image. For example:

 >> info = imfinfo('ngc6543a.jpg');
 >> info.BitDepth

 ans =

     24

As for conversion of 2D to 3D, you may want to look at some previous answers on this topic, such as this or this.
