本論文では,特殊命令コードであるマーカコードを発生せず,かつ新しい制御パラメータを有するJPEG2000符号化画像のための情報半開示方式を提案する.制御パラメータの導入は,半開示の画質,演算量及び不正解除に対する強度に関する制御能力を向上させる.演算量に関する制御能力の向上は,サイズの異なる画像に対して,半開示処理に要する処理負担をほぼ一定にすることを可能とする.この特長は,動画像のリアルタイム処理において重要な役割を果たす.

Two methods for improvement of image-quality in JPEG2000 coding with ROI(Regions of Interest) are proposed in this paper. In JPEG2000, there is a coding unit refered to code-block. We show that it is a problem that the relationship between this co...
