Approximately 40,500 ha of Spartina-dominated marshes died during a drought-induced disturbance in Louisiana. This caused concern because in the absence of recovery, dieback marshes can subside, increasing the present high rates of wetland loss in coastal Louisiana. We assessed the recovery of one such dieback area after hydraulically dredged(More)
Efficient edge detection is accomplished by means of a hierarchical processing scheme which implements spatial frequency channels similarly to processing in biological visual systems. We use such a pyramidal data structure to efficiently create the channels and thereby extract a set of edges from the various scales of the image. The set of selected edges(More)
