T1 Modified Vector Sigma-Filter for the Processing of Multichannel Radar Images and Increasing Reliability of its Interpretation JF Telecommunications and Radio Engineering JO TRE YR 2002 FD 2004-04-19 VO 58 IS 1&2 OP 14 AB A modified vector sigma-filter (MVSF) is presented designed for the processing of multichannel radar images. Based on the standard filtration quality-estimation criteria it is shown that the modification ensures a compromise between the basic properties of the filter. Having a sufficient stability as to disturbances, the MVSF allows substantially suppressing the multiplicative noise and ensuring the preservation of boundaries and of small-sized objects even at relative feeble contrasts. On the test images it is shown that, when evaluating the erodibility of a soil without vegetation, the use of the MVSF (instead of its scalar analog and original image classification) leads to the increase of the accuracy of remote-sensing data classification.
