Does it means to produce a polygon feature layer from a raster?

GDAL has this function - gdal_polygonize

http://www.gdal.org/gdal_polygonize.html

GDAL raster functions are all ported in QGIS as a plugin (i.e Raster) in QGIS.

Download QGIS 1.6.0 and have a look at the Raster. QGIS supports
vector, raster, database, etc.

GdalTools plugin - (Raster)
