Wavelet-based point feature extractor for multisensor image restoration
Hui Henry Li, Yi-Tong Zhou · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
Multi-sensor data such as visual/IR imagery are difficult to register due to the discrepancy in their grayscale characteristics. This paper presents a wavelet-based point feature extraction algorithm to select distinct and consistent point features across images in order to overcome this difficulty. It incorporates local statistical information of the image intensity to locate point features in multi-resolution contour maps generated using the wavelet transform. Experimental results using real multi-sensor data are presented.
