Distinguishing an image of a three-dimensional object from an image of a two-dimensional rendering of an object

A computer usable program product comprising one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices, the stored program instructions comprising:

• program instructions to present a 2D rendering of a 3D subject as an input to a multi-camera apparatus, the multi-camera apparatus operating an image classification model configured to classify a subject viewed via the multi-camera apparatus, and the multi-camera apparatus operating a depth classification model configured to distinguish between a depth characteristic of a 3D subject and a depth characteristic of a realistic 2D rendering of a 3D subject, using depth information provided by viewing a subject via the multi-camera apparatus;
• program instructions to collect, using the multi-camera apparatus, a first depth information corresponding to the input;
• program instructions to provide the first depth information to the depth classification model;
• and
• program instructions to reject, responsive to the depth classification model classifying the input as a 2D rendering, the 2D rendering as being the 3D subject.

A computer system comprising one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:

• program instructions to present a 2D rendering of a 3D subject as an input to a multi-camera apparatus, the multi-camera apparatus operating an image classification model configured to classify a subject viewed via the multi-camera apparatus, and the multi-camera apparatus operating a depth classification model configured to distinguish between a depth characteristic of a 3D subject and a depth characteristic of a realistic 2D rendering of a 3D subject, using depth information provided by viewing a subject via the multi-camera apparatus;
• program instructions to collect, using the multi-camera apparatus, a first depth information corresponding to the input;
• program instructions to provide the first depth information to the depth classification model;
• and
• program instructions to reject, responsive to the depth classification model classifying the input as a 2D rendering, the 2D rendering as being the 3D subject.
