Paper Abstract

This contribution motivates and proposes the new idea of embedding and hiding a highlighting of particular regions within a raster image. Existing approaches tightly combine content and means for highlighting, and thus, do not allow access control to the emphasized contents or a removal of the accentuation. This is overcome by the introduced approach taking advantage of the Depth of Field effect of the Human Visual System for highlighting and features of the JPEG2000 image coding standard for its fast implementation. The proposed method can be applied to already encoded or plain imagery. The achieved results show that hidden context highlighting is rather appropriate for emphasizing pre-defined image regions and able to control the access to the respective contents.
