Otsu Thresholding Segmentation with the 3D ROI Tool

Since its introduction in 2010, the 3D region-of-interest (ROI) operator has aided our users in quantification and volume estimation from their image data.  The prerequisite of any quantification or volume estimation task is an accurate segmentation for the volume of interest.  The 3D ROI tool’s combination of manual, semi-automated, and fully-automated segmentation routines provides a highly complete toolbox with an emphasis on accuracy and efficiency for the user.

Introduction to VivoScript – Part III: Automated Segmentation

Histogram based auto-thresholding (based on Otsu’s algorithm) is a great way to automatically segment two Gaussian distributions of values, e.g. background vs. animal. In this post we are looking into automating this process and placing the segmentation function into a library file so it can be reused in other scripts.
