Abstract

An estimation algorithm for the trajectory of a mark-making object is developed which does not require interactive selection of the region of marks. An adequate measure of the straightness of marks is proposed which allows quantitative evaluation of the performance of the estimation algorithms. Results of experimental studies are given that support the possibility of using the gradient structure tensor to estimate moving object trajectories from images obtained during motion analysis
