Abstract

Intelligent speckle filters promote the efficient usage of PolSAR data. It has been validated that non-local means filter is capable of reducing noise while preserving details. This paper applies a non-local filtering scheme for dual-channel TerraSAR-X PolSAR data. One of the key points in Non-local means filter is the similarity measurement. In this study, detection similarity and Log-Euclidean similarity are used and compared regarding dual-channel PolSAR. The analysis showed that each similarity approach leans to one side of the speckle reduction-detail preservation trade-off.
