Zusammenfassung: | Methods for estimating band-to-band misregistration are of two main types, cross-covariance or Fourier based. Here a general approach is outlined to optimise the use of either method for correcting complex misregistrations in a quick and straight forward manner. Consideration is given to possible feature matching problems associated with multi-resolution processing, and inherent problems with different types of imaging systems. The algorithm described is a simple divide and conquer system that uses predictions of local translations at continually increasing resolutions to form complex transformations. The method has been applied, and currently used to correct the complex misregistrations present in images captured using the DMSV Mkl camera system built by SpecTerra Systems Pty. Ltd. |
