A plugin that enables image annotation/scoring and writes annotations to a .csv file. Plugin provided by the Allen Institute for Cell Science.

The Allen Cell Image Annotator plugin for napari provides an intuitive graphical user interface to create annotation templates, annotate large image sets using these templates, and save image annotations to a csv file. The Allen Cell Image Annotator is a Python-based open source toolkit developed at the Allen Institute for Cell Science for both blind, unbiased and un-blind microscope image annotating. This toolkit supports easy image set selection from a file finder and creation of annotation templates (text, checkbox, drop-down, and spinbox). With napari's multi-dimensional image viewing capabilities, the plugin seamlessly allows users to view each image and write annotations into the custom template. Annotation templates can be written to a json file for sharing or re-using. After annotating, the annotation template, image file list, and the annotation values are conveniently saved to csv file, which can be re-opened for further annotating.

  • Supports the following image types:
    • OME-TIFF
    • TIFF
    • CZI
    • PNG
    • JPEG

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.
