In this paper, a new method for motion flow estimation that considers errors in all the derivative measurements is presented. Based on the total least squares (TLS) model, we accurately estimate the motion flow in the general noise case by combining noise model (in form of covariance matrix) with a parametric motion model. The proposed algorithm is tested on two different types of biological motion,...
Abstract. The root epidermal bulger 1 (reb1) mutant of Arabidopsis thaliana (L.) Heynh. is characterized by a reduced elongation rate of the primary root and by the bulging of many, but not all, root epidermal cells. In this study, we investigated cell wall structure of root epidermal cells in reb1-1 by using serial sectioning, and light and electron microscopy in combination with immuno-cytochemistry...
