Outline of Final Research Achievements

Throughout this research, we have developed an extension of the bilateral filter to multimodal images and high-speed computational algorithms and have devised its application to intelligent image processing with its implementation to computers. The bilateral filter has taken attention as a fundamental algorithm of the computational photography which is an emerging technology having central role for developing next-generation cameras. For the bilateral filter (BF), we have developed a shift-weighted BF, coefficient-inverted BF, segment BF and anisotropic BF. We have applied them to non-photorealistic rendering techniques such as stippling, line drawings, stained glass images and multi-valued half-toning.

Academic Significance and Societal Importance of the Research Achievements

写真の色合いを変えたり、絵画風に変換したりする機能が装備されたカメラはコンピュテーショナルカメラと総称され、市販もされている。本課題研究は、そのコンピュテーショナルカメラの中核技術であるバイラテラル画像処理について、基礎から応用にわたる研究を行ったものである。本研究の成果は、これからのコンピュテーショナルカメラの発展に貢献できると考えられ、さらに広範なコピュテーショナルイメージング技術の進展に寄与できると期待される。
