Illustration Watermarking for Digital Images: An Investigation of Hierarchical Signal Inheritances for Nested Object-based Embedding

摘要

Objective of this research in object-based annotation watermarking is to address the problem of Nested Object-based Embedding for hierarchical object compositions in images. Here it is necessary that each annotation does not interfere with any other annotation within the image and furthermore, it is also desirable that the relationship between annotations can directly be expressed by the structure of the different watermarks. The concept of addressing these research challenges has been structured in two main research tasks: A) Hyperlink-Graph-Concept: Formal model for representing objects and information in hierarchical structures; and B) Formal requirements and general design approach for signal-level watermark inheritance.
