As a engineering requirements we initiated a study using an on-line computer system to analyse grains in a gravitational flow, i.e. a falling stream of particles. Compared with images from a moving conveyor belt, in gravity flow both grains and background appears more and less afflicted by overlaps. This, apart from alleviating the problems of overlapping, implies that the size and shape of grains...
In order to quickly and accurately estimate average size of densely packed aggregate particles on a moving conveyor belt, one problem is motion blur. This paper presents a novel algorithm to restore the blurred image accurately. Moving object or camera motion can cause motion blur in conventional single-exposure photography. Because the exposure time is short, the motion can be seen as constant-speed...
