Multiple View Registration

If more than two data sets are to be fused, then one can merge the data sets incrementally (e.g. (13,61,5) and many others) or simultaneously (2,15,7,4,21,3,28,48,54,49,47,39,16,77). The incremental method is efficient and requires less computer memory but the registration error can accumulate and redundant data are not fully utilised to improve registration. The simultaneous method makes full use of redundant data, but it often involves more intensive computation for optimisation and requires a huge amount of computer memory and, at least theoretically, yields more accurate registration results.
