Introduction

EBRAINS LocaliZoom serial section image viewer provides an intuitive way of navigating high-resolution 2D image series coupled with segmentation overlay, from a web browser. At its core, it is a web-based pan-and-zoom 2D image viewer coupled with a volumetric atlas slicer, and a navigational aid showing the entire image series as a “filmstrip”. Building on the open standard Deep Zoom Image (DZI) format, it is able to efficiently visualise very large brain images in the gigapixel range, allowing to zoom from common, display-sized overview resolutions down to the microscopic resolution without downloading the underlying very large image dataset.

In addition, LocaliZoom is available as a web app in the EBRAINS collaboratory. A Demo dataset is present in a Demo collab: https://wiki.ebrains.eu/bin/view/Collabs/image-registration-and-analysis-demo

Key features:

  • Visualisation of experimental histological section images with atlas overlay

  • Display of the atlas region name when pointing the mouse at the region of interest

  • Annotations and extraction of coordinate points when enabled
