napari-roi-registration
A plugin to perform registration of regions-of-interests in time-lapse data.
Readme
A Napari plugin for the registration of regions of interests (ROI) in a time lapse acquistion and processing of the intensity of the registered data.
The ROI are defined using a Labels layer. Registration of multiple ROIs is supported.
The Registration
widget uses the user-defined labels, constructs a rectangular ROI around each of them and registers the ROIs in each time frame.
The Processing
widget measures the ROI displacements and extracts the average intensity of the ROI, calculated on the area of the labels.
The Subtract background
widget subtracts a background on each frame, calculated as the mean intensity on a Labels layer.
Tipically useful when ambient light affects the measurement.
This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.
You can install napari-roi-registration
via pip:
pip install napari-roi-registration
To install latest development version :
pip install git+https://github.com/GiorgiaTortora/napari-roi-registration.git
A detailed guide which shows how to use the widgets of the napari-roi-registration plugin and how to properly choose the parameters can be found here. A demo video is available at this link. Sample datasets are available.
Register ROIs
button: registration of the entire stack will be performed. When the registration is finished two new layers will appear in the viewer. One layer contains the centroids of the drawn labels while the other contains the bounding boxes enclosing the ROIs.
The registration starts from the currently selected frame. If register entire stack
is selected, the registration will create a new layer for each label, with the registered ROI stacks.Pushing the Process registered ROIs
button, the registered ROIs will be analyzed. The intensity of the registered ROIs (measured on the area of the selected label) and the displacement of the ROIs will be calculated.
If plot results
is selected the plot of displacement vs time index and mean intensity vs time index will appear in the Console.
Choosing the save results
option, an excel file containing ROIs positions, displacements and intensities, will be saved.
Subtract background
button. A new image layer will appear in the viewer. This layer contains the image to which the background was subtracted.Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.
