Yawi3D software provides useful tools for supervised sampling of tumoral masses in CT images.
The software is comprised of two primary components: Yawi2D and Yawi3D. Yawi2D is the fuzzy selection tool (magic wand), which selects ROIs on 2D slices. It is a plugin that utilizes an adaptive algorithm based on the chromatic composition of areas that segments regions with chromatic similarities. This makes it a more powerful implementation of the fuzzy selection tool than ImageJ wand, and it can be applied to a wider spectrum of problems.
Yawi3D, on the other hand, is the software component used to select 3D ROI and is based on Yawi2D. The selection of 3D ROI is a challenging problem as tumoral mass can be a coalescence of different masses, which means that an automatic selection tool has to deal with non-connected ROIs. Yawi3D is yet to be released.
The latest release of Yawi3D includes the following new features: fixed some bugs in the GUI, histogram is drawn with a red gradient to highlight value ranges, it is possible to choose the image format to use when a new image is loaded, support for 8-bit color images, support for big images, when an image is bigger than the screen it is scaled properly and Edit>Settings menu. There are also more checks on image loading for single images and sequences.
Overall, Yawi3D is a highly useful software project that simplifies the selection of tumoral mass in CT images and provides a measure of ROI volume. Its advanced tools make it a great addition to the ImageJ plugin suite.
