Web1 de mar. de 2011 · The core 3-D neuron tracing algorithm is based on three-dimensional (3-D) open-curve active Contour (Snake). It is initiated from a set of automatically detected seed points. Its evolution is ... Web2.1 Deep Open Curve Snake Active contour model, also called snake [15], was first introduced as an algorithm for contour delineation on noisy 2D images. Initial contours are provided by users, then contours are refined through iterative minimization of the energy function, considering

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. (2009) … Ver mais To provide more quantitative information, especially for functional neuronal simulation, the radius is estimated for each point on the snake after tracing.
