cellfinder-napari 0.0.4

Efficient cell detection in large images

cellfinder-napari

Efficient cell detection in large images (e.g. whole mouse brain images)

This package implements the cell detection algorithm from Tyson, Rousseau & Niedworok et al. (2021) for napari, based on the cellfinder-core package.

This algorithm can also be used within the original cellfinder software for whole-brain microscopy analysis.

Instructions

Installation

Once you have installed napari. You can install napari either through the napari plugin installation tool, or directly from PyPI with:

pip install cellfinder-napari

Usage

Full documentation can be found here.

This software is at a very early stage, and was written with our data in mind. Over time we hope to support other data types/formats. If you have any questions or issues, please get in touch by email, gitter or by raising an issue.

Illustration

Introduction

cellfinder takes a stitched, but otherwise raw whole-brain dataset with at least two channels:

• Background channel (i.e. autofluorescence)
• Signal channel, the one with the cells to be detected:

Raw coronal serial two-photon mouse brain image showing labelled cells

Cell candidate detection

Classical image analysis (e.g. filters, thresholding) is used to find cell-like objects (with false positives):

Candidate cells (including many artefacts)

Cell candidate classification

A deep-learning network (ResNet) is used to classify cell candidates as true cells or artefacts:

Cassified cell candidates. Yellow - cells, Blue - artefacts
