Abstract :
A two-step consolidation process is presented that reduces the effect of speckle in the classification result. The degree of consolidation or smoothing can be adjusted using a classification confidence measure and a threshold for the amount of neighborhood agreement needed. Results from AIRSAR ice data shown are compared to a classification result form pre-filtered data.
