| Summary: | 碩士 === 國立中興大學 === 資訊管理學系所 === 101 === The concept of data embedding is to embed a piece of critical information in a host image. We call the critical information critical data and the host image after embedding the critical data an embedded image. For taking photos from an embedded image, various images with very high distortion may be created since various resolutions of camera, different positions the camera located at, distinct regions the zoom focuses on may be employed. The traditional image hiding methods usually cannot precisely derive the critical data from the created variation images. This paper hence proposes a high robust image embedding (HREH) method. The experimental results show that the HREH can precisely extract the critical data from the variation image mentioned above.
