Resumo
Polarimetric synthetic aperture radar (PolSAR)   has achieved a prominent
position  as a remote imaging tool. However,  PolSAR images are
contaminated by speckle noise from the coherent illumination process employed
during the data acquisition.  This noise provides a granular aspect to the
image, making its processing and analysis (such as in edge detection) hard
tasks. This seminar presents seven methods for edge detection in
multilook PolSAR
images.Four stochastic distances, two differences of entropies, and the
maximum likelihood criterion were used under the scaled complex Wishart
distribution. The performance of the discussed detection methods was
quantified and analyzed by means of a Monte Carlo simulation study.
 Additionally,  the detection procedures were applied to PolSAR images. Results
provide evidence that the methods based on Information Theory measures
outperform
the other techniques.
