Abstract: We have developed a motion analysis method that combines the wavelet transform with the flow surface image technique. In dynamic navigation environments, whenever objects move, the projections of the objects onto the image plane also move. These projections build over time spatiotemporal surfaces of their movement and volumes created by the surfaces. This paper presents a new method for the interpretation of optical flow for moving objects from a sequence of images. Flow surface images of the... (Update)
