Open-Curve Snake is a parametric open curve model. Let c(s) = \left( {x(s),y(s),z(s)} \right), s \in \left[ {0,1} \right] , the snake energy to be minimized can be represented as: where E int (c(s)) is the internal energy used to serve as the smoothness constraint: α(s) and β(s) specify the “elasticity” and “stiffness” of a snake … Ver mais Figure 3 shows the computational workflow of our proposed neuron tracing method. It includes preprocessing, tracing and post-processing stages. For images like those from the Neuromuscular dataset of DIADEM … Ver mais In this section, we extend our approach to trace a large batch of image stacks. Figure 11 illustrates an example of 12 image stacks in which 12 … Ver mais The branching point is a very important component of neuronal morphology. Most of the works in current literature detect branch points explicitly. For example, Mohan et al.

Web6 de out. de 2024 · Contour approximation, which uses the Ramer – Douglas – Peucker (RDP) algorithm, aims to simplify a polyline by reducing its vertices given a threshold value. In layman terms, we take a curve and reduce its number of vertices while retaining the bulk of its shape. For example, take a look at Figure 4.
