Abstract：

We　propose　an　improved　interpolation　scheme　for　quincunx-subsampled　images.　Firstly,　Gabor　filters　are　used　to　analyze　the　texture　orientation　of　each　pixel　in　the　quincunx-subsampled　image,　Secondly,　bases　on　reproducing　kernel　space　W22(R)　and　W22(R)　⊗　W22(R)　are　applied　for　interpolation.　Finally,　a　procedure　is　developed　to　reconstruct　the　missing　pixels　based　on　the　above　two　steps.　Experiments　show　that　our　scheme　is　better　than　the　existing　schemes,　especially　in　objective　term.　Furthermore,　applying　it　to　the　system　of　multiple　description　image　coding　with　quincunx　segmentation　can　improve　the　performance　of　that　system.　©　2006　IEEE.
