Abstract

This paper proposes a new method to detect or segment local bright and dark objects using the detail map reconstructed from the wavelet detail sub-bands after wavelet coefficient shrinkage. We found that the reconstructed detail map has the reliable zero-crossing properties at multi-scale edges. We propose the shrinkage of wavelet coefficients based on energy features to remove noise while preserving the details. The local bright and dark objects can be detected by a simple threshold applied on the detail map. The results show that the performance of our method is very promising despite simple structure.
