Abstract
Generally discussed herein are systems, apparatuses, and methods for moving object detection. In one or more embodiments, a method can include computing a central value for each color of each pixel in a series of frames from a static imaging device to create a static reference frame, computing a difference between pixel values of a first frame captured after the series of frames by the static imaging device and a central value of a corresponding pixel value in the static reference frame, comparing the computed differences to a difference threshold, aggregating contiguous pixels corresponding to differences greater than the difference threshold into contiguous segments of pixels, and determining if the contiguous segments correspond to a moving object by registering the contiguous segments to pixels of a frame preceding the first frame.
