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 [...]

Validation of real-time intensity based 2D/3D registration for image guided radiotherapy
No opinion
Patient motion during radiotherapy or intra-fractional motion, is one of the major sources of uncertainty in dose application. 2D/3D registration is an intensity based method used successfully to track tumor motion with the potential to reduce uncertainty. [...]

A Treatment Planning System for the Small Animal Radiation Research Platform (SARRP) based on 3D Slicer
This paper describes the software integration of a treatment planning system (TPS), based on the open-source 3D Slicer package, with the Small Animal Radiation Research Platform (SARRP).The TPS is designed to enable researchers to replicate their clinical [...]

Walk In A Triangulation : Straight Walk
This document describes the implementation in ITK of the Straight Walk in a Triangulation algorithm proposed by Devillers et al. Using the exact discrete geometrical orientation predicate, and the itk::QuadEdgeMesh API of ITK, we propose an efficient [...]

On the Generation of Ground Truth Data for Depth Reconstruction
Acquiring data sets for stereo or multi-view reconstruction with known ground truth is costly and time consuming. Freely available data sets mostly focus on specific scene conditions and might not reflect the intended application scenario. We propose a GPU [...]

Mutable Priority Queue Container
When dealing with functional minimization, or maximization, it can sometimes be solved by a greedy algorithm. To implement greedy algorithm one needs priority queue container, i.e. get for a very low cost the lowest or highest element present in a sorted [...]

Performance Benchmarking the Insight Toolkit
No opinion
This document describes a module for the Insight Toolkit (ITK) to assist in performance benchmarking and a suite of benchmarks for the toolkit. These resources provide metrics to quantify software computational performance. This is a pre-requisite to improve [...]

OpenCL accelerated GPU binary morphology image filters for ITK
No opinion
Binary morphological operations are fundamental tools in image processing but the processing time scales with the number of pixels thus making them expensive operations on the CPU for larger 3D datasets that typically appear in medical imaging. Since erosion [...]

Efficient implementation of kernel filtering
Kernel based filtering is one of the fundamental tools of image analysis and processing. A number of approaches have been developed over the years that allow efficient implementation of such filters even when the kernel size is large. This article reviews [...]

Giving streaming and multi-threading capabilities to non-streamable ITK filters
This document describes a filter able to give streaming and multi-threading capabilities to those filters that can not be easily streamed or multi-threaded. The goal of this document is to explain the implementation of this filter, and how it can be used to [...]

An Optimized N-Dimensional Hough Filter for Detecting Spherical Image Objects
An Insight Toolkit (ITK) algorithm for detection of spherical objects using Hough methods with voting is presented in this paper. Currently, the usage of Hough methods for detecting linear and circular elements exists for 2D images in ITK. The current work [...]

An Open Source, Fast Ultrasound B-Mode Implementation for Commodity Hardware
This document describes an open source, high performance ultrasound B-Mode implementation based on the Insight Toolkit (ITK). ITK extensions are presented to calculate the radio-frequency (RF) signal envelope. A variety of 1D Fast Fourier Transform options [...]

BinShrink: A multi-resolution filter with cache efficient averaging.
No opinion
We present a new filter for the Insight Toolkit (ITK) for reducing the resolution of an image by an integer factor while averaging called BinShrink. This filter provides a new level of performance to ITK for reducing resolution and noise present in an image. [...]

Multidimensional Arrays and the nArray Package
At the Johns Hopkins University’s Engineering Research Center for Computer-Integrated Surgical Systems and Technology (ERC-CISST) laboratory, we have designed and developed a platformindependent C++ software package, called the nArray library, that provides [...]

Efficient contour detection in binary and label images
ly in ITK, the only way to find the contour of the objects in a binary image is to use the BinaryErodeImageFilter, with a kernel of radius 1. This filter is a generic filter, made to support any shape and size of structuring element, and thus is not optimized [...]

Computing Textural Feature Maps for N-Dimensional images
No opinion
This document describes a new remote module implemented for the Insight Toolkit ITK, itkTextureFeatures. This module contains two texture analysis filters that are used to compute feature maps of N-Dimensional images using two well-known texture analysis [...]

Implementation of a 3D thinning algorithm
ITK currently comes with a 2D binary thinning (skeletonisation) method, but does not support 3D or higher. This paper documents a new itkBinaryThinningImageFilter3D and recommends to rename the current filter as itkBinaryThinningImageFilter2D. The 3D [...]

Radial Thickness Calculation and Visualization for Volumetric Layers
Volumetric layers often encountered in medical image analysis are characterized by double and nested bounding surfaces. The thickness of a volumetric layer at a point on the bounding surface is the distance from that point to the opposite surface. There exist [...]
