Abstract
This Paper investigates the use of Wavelets for automatic registration and for onboard processing of remote sensing satellite imagery. The zero tree structure of the wavelet coefficients provides a unique and fast method to predict the location of the control points in a hierarchical fashion. This approach reduced the search space for determining the control points required for image registration. Considering the computation intensive and memory intensive characteristics of remote sensing image registration and the limited computing power of onboard hardware to implement image registration efficiently and effectively with dedicated architecture is of great significance. Due to excellent reconfigurability and convenient design flow, FPGA is proposed for a fast automatic image registration.
