Abstract:
1. A method of improving an infrared (IR) image, the method comprising: capturing a visual image of an object by a visual image sensor; capturing an IR image of the object by an IR image sensor; altering at least one of a resolution of said visual image and a resolution of said IR image; high pass filtering said visual image to extract pixel data representing contours and/or edges in the visual image, wherein the contours and/or edges include those pixels of the visual image that correspond to no or low contrast portions in pixels of the IR image; low pass filtering said IR image to reduce noise in the IR image and/or smooth the IR image; and combining, by a processor, luminance information of the extracted pixel data with luminance information of corresponding pixels in the 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.
