DEF

[A technique] that corrects and improves radiometric values of individual pixels.

CONT

By using adaptive filters a compromise exists between the radiometric enhancement in the homogeneous areas and the preservation of the spatial resolution within the heterogeneous areas (i.e., the textural area or edges). Depending on the local heterogeneity degree of the target, pixels are weighted with a value ranging from the local mean to the raw intensity values.

OBS

radiometric enhancement: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
