Feature selection is becoming a major component of object-based classification as numerous features of segmented object become available. Although common feature selection methods in object-based classification are acknowledged, wrapper-based methods remain an issue due to the diversity of accuracy assessment methods. This letter presents a new wrapper approach using polygon-based cross validation...
Point Spread Function (PSF) estimation is a key issue influencing the quality of imagery restoration. There are many PSF estimation methods for optical imagery but few for SAR imagery. This paper puts forward a new method of PSF estimation for restoration of SAR imagery. By setting corner reflectors in the field, according to the brightness and scattering features, the PSF of SAR imagery can be simulated...
