Algorithm Comparison

This table compares all available algorithms to help you choose the right one for your use case.

Algorithm	Speed	Precision	Best For
Geodesic Distance	Fast	High	General use, most tissue types
Watershed	Medium	High	Marker-based segmentation, clear boundaries
Random Walker	Medium	High	Noisy images, probabilistic segmentation
Level Set	Slow	Very High	Irregular boundaries, high precision needed
Connected Threshold	Very Fast	Low	Quick rough segmentation, uniform regions
Region Growing	Fast	Medium	Homogeneous regions with clear boundaries
Threshold Brush	Very Fast	Variable	Simple threshold painting, when boundaries are clear

When to Use Each Algorithm

For Speed

If you need fast results, use Threshold Brush or Connected Threshold.

For Precision

If you need precise boundaries, use Level Set or Geodesic Distance.

For Noisy Images

If your image has noise, use Random Walker which is robust to noise.

For General Use

Geodesic Distance is the recommended default for most use cases.
