摘要
A system and method for processing a daytime IR image to discriminate between solar glints and hotspots, where the latter represent man-made activity. Two spectrally distinct thermal wavelength bands are defined and respective spectral intensities are detected for a corresponding pixel in an image. A figure of merit is calculated as a function of the detected spectral intensities. The calculated figure of merit is compared to a predetermined rule to determine whether the corresponding pixel is a glint or a hotspot.
