A subset of the true optical flow can be extracted by constructing a vector field that represents image gradients and then tracking vectors in this vector field. This pseudo-flow (p-flow) subset ...

Abstract: Snakes, or active contour models, have been widely used in image segmentation. In this paper, a new type of dynamic external force for snakes named directional gradient vector flow (DGVF) is ...

Repository contains code and visualizations that demonstrate concepts of scalar and vector fields using the Julia programming language. Explore 3D surface plots and 2D contour plots showcasing scalar ...

Abstract: As a reliable personal identification method, iris recognition has been receiving increasing attention. Based on the theory of robust statistics, a novel geometry-driven method for iris ...

Hello! It's been a while but I have a new question! I would like to use the orientation of the lithology (i.e. the direction of greatest dip) in each grid cell as an ...
