AISIR: Automated Inter-sensor/Inter-band Satellite

7 An automated registration system named AISIR (Automated Inter-sensor/Inter8 band Satellite Image Registration) has been designed and implemented for 9 the purpose of registering satellite images acquired using different sensors and 10 spectral bands. Sensor and environmental noise, contrast non-uniformities, 11 and inter-sensor and inter-band intensity mapping differences are addressed 12 in the AISIR system. First, a novel modified Geman-McClure M-estimation 13 scheme using a robust phase-adaptive complex wavelet feature representa14 tion is introduced for robust control point matching. Second, an iterative 15 refinement scheme is introduced in the AISIR system for improved control 16 point pair localization. Finally, the AISIR system introduces a robust map17 ping function estimation scheme based on the proposed modified Geman18 McClure M-estimation scheme. The AISIR system was tested using various 19 multi-spectral optical, LIDAR, and SAR images and was shown to achieve 20 better registration accuracy than state-of-the-art M-SSD and ARRSI regis21 tration algorithms for all of the test sets. 22
