Outline of Research at the Start

一般に画像の減色(階調圧縮,量子化) は非可逆圧縮であり, 減色された画像から原画像を完全に再現する手法は現在のところ存在しない. 本研究では, シグマデルタ型セルラーニューラルネットワーク(SD-CNN) による可逆階調圧縮に基づく新しい画像圧縮手法を創成する.網膜情報処理に基づく提案手法により,従来の階調圧縮手法とは異なる新たな圧縮方式への道を拓き,画像情報の2次元パルス化による圧縮伝送を模索する.

Outline of Final Research Achievements

In this research project, we have developed a method to decompose input data into binary data sequences and integrate them using a multistage digital integrator, thereby restoring the input data without degradation. In our method, two-stage SD-CNN, a mimic of converting external image information into biological pulses in the retina of a living body, is employed. We have also realized a highly accurate bit-depth expansion technique that efficiently reconstructs a visually lossless quality image from a low-gradation image.

Academic Significance and Societal Importance of the Research Achievements

学術的意義として,生体の網膜における情報処理を応用することで,画像を含む様々なデータを可逆復元できることを明らかにした点が挙げられる.また,階調圧縮のみならず,海中など狭帯域の通信環境に適合するデータ伝送方式への応用が可能である点に社会的意義がある.
