Abstract
Pixel intensity differences between pixel values of a region in a first image frame and the region in a second image frame are determined, where the region in the first image frame includes an image of a spherical object, with no overlapping spherical object in the second image frame. Based on the pixel intensity differences, the region of the first image frame is thresholded into foreground pixels and background pixels until the background pixels make up more than a predefined percentage of the region of the first image frame. From the background pixels, a subset of the background pixels located along a plurality of paths that radially extend outward from a center of the region in different angular degrees is selected. The subset of the background pixels is filtered by applying a filter, where the filtered subset is detected as edge pixels.
