Freehand Tool

The freehand segmentation tool allows precision region placement with built-in nudge editing for quick manual fine tuning without needing to switch tools.

Spline Tool

The spline contour segmentation tool allows you to create smooth contours with configurable spline types for detailed control.

Livewire Tool

The livewire contour tool automatically detects and snaps to region borders as you trace, making it easier to accurately outline.

Sculptor Tool

We have a brand new sculptor tool with a dynamic brush size that automatically detects and adjusts to the region border, allowing intuitive editing. The dynamic brush can be placed inside the region to expand it, or outside the region to erase.

Combine & Modify Multiple Contours

In addition to the drawing and editing tools, we've added powerful new logical operation functionality to take contour manipulation to the next level. Using the new combine tool, overlapping segments can be joined, intersect, or subtracted from each other, with the option to create a new segment from the result.

With the simplify contours tool, filling holes or removing small islands in a region is as simple as a click. If a generated contour needs to be refined, there are also now one click tools to smooth all edges and remove extraneous points from contours.

And of course, all the logical operation tools are compatible with undo/redo!

Unified Segmentation Panel

With the addition of new contour tools, we needed a unified approach to the segmentation panel, allowing seamless switching between labelmap and contour workflows. Our new segmentation panel uses a tab design to deliver the full suite of contour and labelmap tools with one click to switch between them.

OHIF Governance

After many revisions, input from key stakeholders, and community feedback, OHIF's official governance framework is now effective. Governance is a critical component of any open source project, and OHIF is no exception. With the new framework in place, we aim to provide clear, consistent project guidelines that ensure the bond between contributors and maintainers remains strong and sustainable long term.

The OHIF team will regularly publish updates to the public documentation and maintain historical versioning for the community to reference in a new dedicated repo. Check out the OHIF governance here and feel free to drop us a line if you have any feedback!
