Paper Abstract

Many remote sensing applications require comparison between satellite images acquired over a span of years. Commercially available radar images, such as ERS images, have misalignments between images ranging up to 100 pixels for images acquired a few years apart. The registration of these images is rendered difficult due to three reasons. (i) The volume of data to be processed makes speed of execution key issue. (ii) The uncertainty regarding scene contents rules out the use of any predefined 'target class'. (iii) The long time interval between images leads to large scene content variations. This requires the matching process to be very robust.
