This plugin has an experimental version available!

This plugin creates a raster region using a point clicked on the image, known as a seed.

The region starts at the seed and expands by comparing the seed's RGB values with those of neighboring pixels.
If the difference in values is less than a defined threshold (for each channel), the region grows.

Once the region is defined, a polygon is created.
The user can then choose the vector operation to be performed with this polygon on the active vector layer:
Add, Difference, Clip, or Union.

This plugin is part of the Brazilian Fire Information System (Sisfogo),
develop by National Center to Prevent and Combat Forest fires (Prevfogo/Ibama).
