Systems, devices, and methods including: an optical gas imaging (OGI) camera; a processor in communication with the OGI camera, the processor configured to: capture at least two images of a scene with the camera; compare the captured at least two images to determine at least one of: a motion associated with a movement of the camera and a motion associated with a movement of a gas plume; apply a color to each pixel of the captured images based on at least one of: a direction of movement and a velocity of movement between the at least two captured images; subtract pixels from the colored pixels associated with the movement of the camera; and generate an image of an output of a gas plume based on the subtracted pixels and the applied color pixels.
