Abstract: This paper provides a kind of algorithm that is completed in compressed domain and discusses a four-image composition method in detail including composition principle, composition algorithm and program implementation. Finally, its experiments result is given and compared with that of implementation in analog domain, we can find its quality is enhanced and cost is lowered largely.
