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...
