Method, system and computer program product for segmenting an image

A system for segmenting an image, the system comprising:

• a combination of electronic circuitry components for:
• generating a first depth map in response to a first stereoscopic image from a camera, wherein the first depth map includes first pixels having valid depths and second pixels having invalid depths;
• generating a second depth map in response to a second stereoscopic image from the camera, wherein the second depth map includes third pixels having valid depths and fourth pixels having invalid depths, wherein the second and fourth pixels have a first type of invalid depths, wherein the first depth map includes fifth pixels having a second type of invalid depths, and wherein the second depth map includes sixth pixels having the second type of invalid depths;
• generating a first segmentation mask in response to the first pixels and the third pixels;
• generating a second segmentation mask in response to the second pixels and the fourth pixels;
• generating a third segmentation mask in response to at least the sixth pixels;
• and, in response to the first, second and third segmentation masks, determining whether the second stereoscopic image includes a change in comparison to the first stereoscopic image.

A computer program product for segmenting an image, the computer program product comprising:

• a non-transitory computer-readable medium;
• and
• a computer-readable program stored on the non-transitory computer-readable medium, wherein the computer-readable program is processable by an information handling system for causing the information handling system to perform operations including:
• generating a first depth map in response to a first stereoscopic image from a camera, wherein the first depth map includes first pixels having valid depths and second pixels having invalid depths;
• generating a second depth map in response to a second stereoscopic image from the camera, wherein the second depth map includes third pixels having valid depths and fourth pixels having invalid depths, wherein the second and fourth pixels have a first type of invalid depths, wherein the first depth map includes fifth pixels having a second type of invalid depths and wherein the second depth may includes sixth pixels having the second type of invalid depths;
• generating a first segmentation mask in response to the first pixels and the third pixels;
• generating a second segmentation mask in response to the second pixels and the fourth pixels;
• generating a third segmentation mask in response to at least the sixth pixels;
• and, in response to the first, second and third segmentation masks, determining whether the second stereoscopic image includes a change in comparison to the first stereoscopic image.
