Natural Coherency without Noise?

26 November 2018 1 8K Report

Hi Everyone,

I need the natural coherency from my study area in the processing of radar images using InSAR technique but I don't would like to apply any Multi-looking on used images to keep the resolution and the actual coherency of land. On the other hand, I face to some noise in the results of radar processing if we don't use the multi-looking. Can anybody help and guide me to do it?

Best regards,

Sayyed

Dear Seyyed

Salaam

Non-local filters give you a good trade-off between preserving resolution and noise level. You can find more in the following link. The processing time is high in CPU-implementations and you can find the GPU implementation in the second link implemented by Geral Baier from TUM.
