Methods of providing a diagnosis using a digital code associated with an image are provided including collecting a multidimensional image, the multidimensional image having at least two dimensions extracting a two dimensional subset of the multidimensional image reducing the multidimensional image to a first code that is unique to the multidimensional image based on the extracted two dimensional image comparing the first unique code associated with the subject to a library of reference codes, each of the reference codes in the library of reference codes being indicative of a class of objects determining if the subject associated with the first unique code falls into at least one of the classes of objects associated with the reference codes based on a result of the comparison and formulating a diagnostic decision based on the whether the first unique code associated with the subject falls into at least one of the classes associated with the reference code. Related systems and computer program products are also provided herein.
