1. A computer-implemented method for image capture enhancement, comprising: activating a sequence of infrared emissions, by one or more emitters in an environment space monitored by a camera for capturing images of the environment space, wherein the sequence of infrared emissions is synchronized with a frame counter of the camera; receiving captured image frames from the camera, wherein the captured image frames comprise a first frame captured during an emission, and a second frame, adjacent to the first frame, captured outside the emission; subtracting the second frame from the first frame to provide an image of a reflected infrared component; removing, from the reflected infrared component, a previously obtained background image of the environment space to enhance a subject in the image; and outputting a resultant image for processing.
