Paper Abstract

A new technique for local contrast enhancement using rank-order filters with spatially adaptive neighborhoods is proposed. The technique is based on the unsharp masking operation. However, instead a linear lowpass filtering we use various rank-order smoothing operations. The smoothing is performed over the pixels of spatially adaptive neighborhoods of details to be enhanced and their surrounding backgrounds. Various rank-order filters for local enhancement of small and middle-size details are implemented. Computer simulation results using a real aerial image are provided and discussed.
