DISCRETE WAVELET TRANSFORM BASED BLIND WATERMARKING ALGORITHM FOR GRAY IMAGE AND COLOR IMAGE
碩士 === 大同大學 === 電機工程研究所 === 89 === In this thesis, we present a blind watermarking algorithm based on the Discrete Wavelet Transform (DWT) and we extract the watermarks without the original image. We use a recognizable binary watermark image to embed into the low frequency subbands of DWT...
