Edge를 이용한 1-bit 영상의 원본 증명용 워터마킹 알고리즘
Watermarking Algorithm for 1-bit Image Authentication using Edges
초록
This paper proposes a new watermarking algorithm to embed data in 1-bit images using edges for protecting illegal copies or modifications. This method is based on edge detection to decide the most invisible region. This paper also introduces a new shuffling method which embeds data in each blocks uniformly and finds Positions under the limited attacks. In experiment, we compare the proposed shuffling method with M. Wu's method.
