We are pleased to announce the release of Tomviz 1.2.1 today, made two weeks after Tomviz 1.2.0 was released. The 1.2.1 release fixes a few minor bugs discovered at the Frontiers of Electron Tomography short course following the workshop at Berkeley Lab where we presented a Tomviz tutorial on Wednesday afternoon. This release was made […]

Don’t worry about the pixel type In previous posts about the Insight Toolkit (ITK), we talked about installing ITK Python packages from PyPI, sharing data between ITK and NumPy, and even create your own ITK module with its Python wrapping automatically generated. This post will use examples from the NumPy post and explain in more […]

A vtk.js rendering of a large-scale oceanic dataset with 5.2 million triangles. Rendering three-dimensional (3D) meshes and volumetric datasets became possible on the web years ago with the introduction of WebGL. Since that time, several libraries have gained popularity by supporting 3D data rendering in the web browser. These libraries often focus on gaming; they […]

Recently, the Insight Toolkit (ITK) was made available in binary Python packages. While these packages make the core high-performance, multi-dimensional image analysis capabilities more accessible in Python, the brilliant researchers in the broader ITK community have additional advanced algorithms to contribute. They can now distribute extensions to the toolkit as Python packages from ITK Modules! […]

Kitware Maps Development of Toolkit for Image and Video Analysis Kitware released version 1.1 of the Kitware Image and Video Exploitation and Retrieval (KWIVER) open-source toolkit before the 2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR). Members of the computer vision team at Kitware appeared at the CVPR industry exposition to accent this […]

Fully coupled multi-component and multi-scale modeling systems such as Regional Earth System Model (RegESM) are used to represent and analyze complex interactions among physical processes. A typical application of RegESM can produce tens of terabytes of raw data. This data determines the resolution of the spatial grid, the length of the simulation and the number […]

NVIDIA Index™ Plug-in for ParaView Gets Updated NVIDIA Index™ is a commercial software that enables the use of graphics processing unit (GPU) clusters for real-time visualization of large volumetric and polygonal datasets. ParaView users became able to try Index™ for volume rendering in ParaView for the first time in 2015. Since then, new efforts have […]

On behalf of the Insight Segmentation and Registration Toolkit (ITK) Community, we are happy to announce the release of ITK 4.12.2! ITK is an open-source, cross-platform library for multidimensional image analysis. Download ITK This is a patch release that fixes critical issues, regressions, documentation, and compiler support. This release includes better compatibility when building an […]

How do we extract meaningful information from scientific images in spite of ubiquitous noise? Edge-preserving image smoothing removes noise as a pre-processing step for visualization or analysis. A number of edge-preserving image processing filters are available in the Insight Toolkit (ITK), such as the bilateral image filter. An anisotropic diffusion filter that delivers excellent edge-preserving […]

Following the trend started earlier this year, ParaView 5.5 will support the ability to dock the Python shell in the UI. Docking makes it easier to always have easy access to the Python shell for those among us who enjoy writing code as much as clicking on buttons. A thing to note is that while the […]

Recently, a lot of effort has gone into web-based projects that Kitware manages, including: ParaViewWeb, a JavaScript library that developers can employ to build applications that run on the Web and use the Visualization Toolkit (VTK) or ParaView as the backend; vtk.js, a rendering library for high-performance computing; and Visualizer, an application that renders and […]

On behalf of the Insight Segmentation and Registration Toolkit (ITK) Community, we are happy to announce the release of ITK 4.12.1! Download ITK This is a patch release that fixes critical issues, regressions, documentation, and compiler support. Of the numerous issues addressed in this release, most notable are fixes to enable compilation of ITK on […]

ParaView 5.4.1 is now available for download. This bug fix release addresses a number of problems in 5.4.0, including: The black render window observed on some systems when FXAA was enabled or an object’s opacity was less than 1 has been fixed. Field output for cells with non-straight edges has been corrected. Derivatives for quadratic triangles […]

We previously announced that the ITK Python wrapping is now available in the Python Package Index (PyPI) [1]. Starting to develop Python scripts using ITK filters is one command line away: python -m pip install itk Python is a scripting language that allows fast development and is widely used in the scientific community. You can […]

This blog article presents an overview of the work being done in collaboration with Emory University on an ongoing NIH grant funded project for the development of informatics tools for the web-based management, visualization, and analytics of digital histopathology data. This project is being executed by a tight collaboration between the members of the Medical […]

Introduction The post presents texture quantification algorithms that provide a statistical description of the local texture of a 2D, 3D or N-D image.  The N-Dimensional texture maps are generated with a high performance algorithm and multi-threaded implementation in the Insight Toolkit (ITK). The software is packaged for Python and in a 3D Slicer extension. We […]

scikit-build is an improved build system generator for CPython C extensions. It provides better support for additional compilers, build systems, cross compilation, and locating dependencies and their associated build requirements. The project started during the 2014 SciPy Conference Sprints by Jean-Christophe Fillion-Robin, Michael Sarahan, Matthew McCormick, and Anthony Scopatz out of frustration with how difficult […]

Thanks to EDF funding, new capabilities for data analysis is making its debut in ParaView and VTK based on OpenTURNS. OpenTURNS is an open source initiative for the Treatment of Uncertainties, Risks’N Statistics, and is now an optional dependency of VTK. It takes the form of an optional VTK module that can be requested to […]
