Abstract: Systems and methods disclosed herein, in accordance with one or more embodiments, provide for indicating gas movement in a scene having a background and an occurrence of gas, and comprise obtaining a sequence of at least two thermal image frames of said scene recorded at different points of time, automatically identifying, in each image frame of said sequence of thermal image frames, a set of pixel coordinates representing gas above a predetermined concentration threshold present in the imaged scene at the point of time at which the image frame was recorded, and automatically determining the location of each of said sets of pixel coordinates in the imaged scene. The systems and methods further comprise at least one of automatically generating a visual presentation image of said scene in which the location of each of said sets of pixel coordinates in relation to the location of each of said other sets of pixel coordinates is visualized, and/or automatically determining a direction of gas movement based on the location of each of said sets of pixel coordinates in relation to the location of each of said other sets of pixel coordinates.
