Adaptive Moment Estimator (Adam) Optimizer in ITK v3
No opinion
This document describes an ITK class implementing an Adaptive Moment Estimator (Adam) optimizer algorithm within the Insight Toolkit ITK www.itk.org. Adam is an adaptive gradient descent optimizer, which independently adaptively estimates the gradient descent [...]

A Gradient Descent Trust Region Optimizer
starstarstarstarstar
This document describes a new simple gradient descent optimizer which is a potential replacement or supplement for RegularStepGradientDescentOptimizer. The optimizer requires only the gradient of the parameters and uses a simple linear model internally. [...]

Deformable Registration with Discontinuity Preservation using Multi-Scale MRF
No opinion
Deformable (2D or 3D) medical image registration is a challenging problem. Existing approaches assume that the underlying deformation is smooth. This smoothness assumption allows for solving the deformable registration at a coarse resolution and interpolate [...]

A Tutorial on Combining Nonlinear Optimization with CUDA
No opinion
Nonlinear optimization is a key component of many image registration algorithms. Improving registration speed is almost always desirable. One way to do this is to accelerate the optimization cost function using a parallel implementation. The purpose of this [...]

ITK-based Registration of Large Images from Light Microscopy: A Biomedical Application
starstarstarstarstar
Inactivation of the retinoblastoma gene in mouse embryos results in morphological changes in the placenta, which has been shown to affect fetal survivability. The construction of a 3D virtual placenta aids in accurately quantifying structural changes [...]

Cumulative Gaussian Curve Fitter for Boundary Parameterization
starstarstarstarstar
We have previously developed an algorithm for locating boundaries in an image with sub-pixel resolution, as well as estimating boundary width and image intensity within the adjoining objects. The algorithm operates by finding the parameters of a cumulative [...]

Integration of Geometrical Boundary Conditions on Soft Tissue Characterization under large deformation
starstarstarstarstar
Soft tissue characterization with finite element (FE) modeling is important to develop a realistic model for medical simulation, since it is possible to display complex tool-tissue interactions during medical interventions. However, it is difficult to [...]
