Uniform　image　partitioning　has　been　achieved　on　Spiral　Architecture,　which　plays　an　important　role　in　parallel　image　processing　on　many　aspects　such　as　uniform　data　partitioning,　load　balancing,　zero　data　exchange　between　the　processing　nodes　et　al.　However,　when　the　number　of　partitions　is　not　the　power　of　seven　like　49,　each　sub-image　except　one　is　split　into　a　few　fragments　which　are　mixed　together.　We　could　not　tell　which　fragments　belong　to　which　sub-image.　It　is　an　unacceptable　flaw　to　parallel　image　processing.　This　paper　proposes　a　method　to　resolve　the　problem　mentioned　above.　From　the　experimental　results,　it　is　shown　that　the　proposed　method　correctly　identifies　the　fragments　belonging　to　the　same　sub-image　and　successfully　collects　them　together　to　be　a　complete　sub-image.　Then,　these　sub-images　can　be　distributed　into　the　different　processing　nodes　for　further　processing.　©　Springer-Verlag　Berlin　Heidelberg　2003.
