Adaptive watermarking in the DCT domain
نویسندگان
چکیده
An adaptive watermarking technique is introduced in this work. A regional perceptual classi er is employed to assign a noise sensitivity index to each region. The watermark is inserted in the original image according to this index by using block DCT. The detection of the watermark is designed to achieve a desired false alarm probability.

متن کاملA Removable Visible Image Watermarking Algorithm in DCT Domain
In this work, a removable visible watermarking scheme, which operates in DCT domain, is proposed for combating copyright piracy. First, the original watermark image is divided into 16×16 blocks and the preprocessed watermark to be embedded is generated by performing element-by-element matrix multiplication on the DCT coefficient matrix of each block and a key-based matrix. The intention of gene...
متن کاملOblivious Image-Adaptive Watermarking Using Quantization Index Modulation
This paper proposes a new oblivious imageadaptive watermarking technique which utilizes a visual model in the discrete cosine transform (DCT) domain and is based on quantization index modulation. In this scheme, the image is watermarked by modifying selected DCT coefficients of image blocks under a constraint specified by the visual model. The binary watermark is recovered from the watermarked ...
