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. [...]

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 [...]

Phase Correlation Method for ITK
starstarstarstarstar
Phase Correlation Method (PCM or SPOMF - Symmetric Phase-Only Matched Filter) is a well known image registration method, that exploits Fourier Shift Theorem property of Fourier Transform. Even though it is limited to estimate only shifts between two images, [...]

Non-rigid Groupwise Registration using B-Spline Deformation Model
starstarstarstarstar
In this work, we extend a previously demonstrated entropy based groupwise registration method to include a non-rigid deformation model based on B-splines. We describe an open source implementation of the groupwise registration algorithm using the [...]

Adapting the ITK Registration Framework to Fit Parametric Image Models
starstarstarstarstar
The image registration framework in the Insight Tookit offers a powerful body of code for finding the optimal spatial transform that registers one image with another. However, ITK currently lacks a way to fit parametric models of image pixel values to an [...]
