Hiding Data in Blue-Noise Halftone Images by Hilbert Curve Decomposition

碩士 === 輔仁大學 === 資訊工程學系 === 97 === In this thesis, we present a simple but novel method, which does not require the original image in encoding and decoding process, to embed watermarks into blue noise halftone images by pairing the sub-images derived from Hilbert curve decomposition. The proposed met...

The proposed method hides data by swapping neighboring pixels along Hilbert curve. We explore the properties of the sub-image pair in depth. The experiments show that the technique is sufficiently robust against the cropping and tampering, rotation and salt and pepper tampering attacks. Brian K. Lien 連國珍 2009 學位論文 ; thesis 51 zh-TW
