직교 변환을 사용하는 워터마킹 방법은 손실 압축과 같은 비기하학적 수정에 대해 매우 강력하지만 이미지 변환이나 자르기에 대해서는 견고성을 확보하기가 어렵습니다. 본 보고서는 워터마크 데이터를 이미지의 주파수 성분에 삽입하고 이미지의 이동으로 인해 발생하는 계수의 위상차를 고려하여 해당 데이터를 검출함으로써 이미지 이동 및 자르기와 같은 기하학적 수정에 대한 견고성을 높이는 워터마킹 방법에 대해 설명합니다. 실험 결과는 비기하학적 이미지 변경과 이미지 변환 및 자르기에 대해 이 방법의 견고성을 보여줍니다.

Abstract: Watermarking methods that employ orthogonal transformations are very robust against non-geometrical modifications such as lossy compression, but attaining robustness against image translation or cropping is difficult. This report describes a watermarking method that increases robustness against geometrical modifications such as image translation and cropping by embedding watermark data in the frequency component of an image and detecting that data by considering the phase difference of the coefficients that results from translation of the image. Experimental results demonstrate the robustness of this method against both non-geometrical image changes and image translation and cropping.
