Abstract: An image enhancement method for video analysis or automatic video surveillance systems has at least one image acquisition device, through which an IR thermal spectrum image is captured from an area of space, a scene calibration system and a detection system, through which at least one object type is detected. The method includes at least one processing stage in which the contrast of the captured image is enhanced by the image acquisition device through the image's depth or scene information obtained directly or indirectly by the scene calibration system or entered manually by the user.

Abstract: A non-transitory computer readable storage medium includes a computer-readable code for executing a method of video playback, capable of displaying a video file in a three-dimensional environment (2) from any perspective, by projecting two-dimensional frames (1) of the video file on said environment (2), according to a position and perspective assigned to the frame (1).
