R-letter of August 2013 - IEEE Communications Society

IEEE COMSOC MMTC R-Letterremove the error from the mean trajectory, they fit atrajectory to a second-order polynomial, which issufficient to quantify the general shape of the motion.The color at each point on the arrows is proportionalto the speed of the motion. Only directional arrows ofsignificant length are kept. The final image withoverlapping arrows is then rendered.The proposed method was tested on two balletsequences and two recorded videos containingcomplex motions. The results demonstrate that evenwith occlusion and low quality video shots taken witha shaky hand-held camera, the output motiondepictions are satisfactory. Though more tests couldhave further validated the robustness of the approach,I find this paper interesting and can inspire furtherresearch on motion data analysis.References:[1] J. Assa, Y.
