Detects blobs in images

---

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

This plugin consists of two widgets:

1. Detects blobs on images
2. Convert points layer to labels layer

---

Detects blobs on images

This widget uses scikit-image's blob detection algorithms to detect bright blobs on dark backgrounds.

Parameters

• method: Laplacian of Gaussian (most accurate) or Difference of Gaussian (faster approximation)
• image: Image layer for blob detection. Can be a 2D, 3D, or higher dimensionality image.
• dimensionality: users can specify if the image is 2D(+t) or 3D(+t).
• min sigma: the smallest blob size to detect
• max sigma: the largest blob size to detect
• threshold: the lower the threshold, the more low intensity blobs are detected.

Output

Blobs are represented by the Points layer. The size of each blob is proportional to Points.feature['sigma'], which signifies the scale at which the feature point was found.

Convert points layer to labels layer

This widget takes a points layer and converts it into a labels layer, with the image dimension matching the selected image layer. By converting points to labels, users can leverage feature extraction functions that are available to labels to the detected points.
