A Wavelet – Based Point Feature Extractor For Multi-Sensor Image Registration

摘要

Multi-sensor data such as visual/IR magery are difficult to register due to discrepancy in their grayscale characteristics. This paper presents a wavelet a wavelet-based point feature extraction algeritlun to select to distinct and consistent point features across images in order to overcome this diffidently. 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
