Abstract
The present disclosure relates to combination of images. A method according to an embodiment comprises: receiving a visual image and an infrared (IR) image of a scene; extracting high spatial frequency content from said visual image; and combining said extracted high spatial frequency content from said visual image with said IR image, wherein a resolution for the visual image and the IR image are substantially the same, to generate a combined image.
Claims25
A method, comprising:
- receiving a visual image of a scene captured using a visual image sensor;
- receiving an infrared (IR) image of at least a portion of the scene captured using an IR image sensor;
- extracting, from the visual image, pixel data representing high spatial frequency content of said visual image, wherein the high spatial frequency content includes contours and/or edges that show no or low contrast in the IR image;
- and
- combining, by a processor, luminance information of said extracted pixel data from said visual image with luminance information of corresponding pixels in said IR image to augment the IR image with the contours and/or edges from the visual image, wherein the augmented IR image comprises temperature information that is unaltered by the combining.
A non-transitory computer-readable medium storing computer program code which, when executed by a processor, causes the processor to perform a method comprising:
- receiving a visual image of a scene captured using a visual image sensor;
- receiving an infrared (IR) image of at least a portion of the scene captured using an IR image sensor;
- extracting, from the visual image, pixel data representing high spatial frequency content of said visual image, wherein the high spatial frequency content includes contours and/or edges that show no or low contrast in the IR image;
- and
- combining luminance information of said extracted pixel data from said visual image with luminance information of corresponding pixels in said IR image to augment the IR image with the contours and/or edges from the visual image, wherein the augmented IR image comprises temperature information that is unaltered by the combining.
An imaging device, comprising:
- a visual image sensor for capturing a visual image;
- an infrared (IR) image sensor for capturing an IR image;
- and
- a processor adapted to:
- extract, from the visual image, pixel data representing high spatial frequency content of said visual image, wherein the high spatial frequency content includes contours and/or edges that show no or low contrast in the IR image, and
- combine luminance information of said extracted pixel data from said visual image with luminance information of corresponding pixels in said IR image to augment the IR image with the contours and/or edges from the visual image, wherein the augmented IR image comprises temperature information that is unaltered by the combining.
