A requirement for understanding morphogenesis is being able to quantify expansion at the cellular scale. Here, we present new software (RootflowRT) for measuring the expansion profile of a growing root at high spatial and temporal resolution. The software implements an image processing algorithm using a novel combination of optical flow methods for(More)
This paper presents a new technique that couples tensor based image flow with robust statistical estimation models to produce dense accurate velocity fields. The 3D orientation structure tensor of the spatiotemporal varying light intensity field is used to estimate local non-rigid image motions. Previous work has shown that in highly uniform regions that(More)
