Abstract
Aspects of the present disclosure relate to multi-spectrum visual object recognition. A first image corresponding to visible light and a second image corresponding to invisible light with respect to an object can be obtained. A first contour of the object can be identified based on the first image. A second contour of the object can be identified based on the second image. The first contour of the object and the second contour of the object can be integrated to generate a multi-spectrum contour of the object. The object can be recognized using the multi-spectrum contour of the object.
Claims18
A computer-implemented method comprising:
- obtaining, by one or more processors, a first image corresponding to visible light and a second image corresponding to invisible light with respect to an object;
- identifying, by the one or more processors, a first contour of the object based on the first image;
- identifying, by the one or more processors, a second contour of the object based on the second image, wherein the first contour is covered at least in part by an invisible light-transmissive obstacle and the second contour is not blocked by the invisible light-transmissive obstacle;
- integrating, by the one or more processors, the first contour of the object and the second contour of the object to generate a multi-spectrum contour of the object;
- and
- recognizing, by the one or more processors, the object using the multi-spectrum contour of the object.
A system comprising:
- a computer-readable storage medium storing instructions, which, when executed by a processor, is configured to cause the processor to perform a method comprising:
- obtaining a first image corresponding to visible light and a second image corresponding to invisible light with respect to an object;
- identifying a first contour of the object based on the first image;
- identifying a second contour of the object based on the second image, wherein the first contour is covered at least in part by an invisible light-transmissive obstacle and the second contour is not blocked by the invisible light-transmissive obstacle;
- integrating the first contour of the object and the second contour of the object to generate a multi-spectrum contour of the object;
- and
- recognizing the object using the multi-spectrum contour of the object.
A computer program product comprising one or more computer readable storage media having program instructions collectively embodied therewith, the program instructions executable by one or more processors to cause the one or more processor to perform a method comprising:
- obtaining a first image corresponding to visible light and a second image corresponding to invisible light with respect to an object;
- identifying a first contour of the object based on the first image;
- identifying a second contour of the object based on the second image, wherein the first contour is covered at least in part by an invisible light-transmissive obstacle and the second contour is not blocked by the invisible light-transmissive obstacle;
- integrating the first contour of the object and the second contour of the object to generate a multi-spectrum contour of the object;
- and
- recognizing the object using the multi-spectrum contour of the object.
