Image watermarking
G06T2201/0051
Embedding of the watermark in the spatial domain
G06T2201/0052
Embedding of the watermark in the frequency domain
G06T2201/0053
Embedding of the watermark in the coding stream, possibly without decoding Embedding of the watermark in the compressed domain
G06T2201/0061
Embedding of the watermark in each block of the image
G06T2201/0062
Embedding of the watermark in text images
G06T2201/0063
in relation to collusion attacks
G06T2201/0064
for copy protection or copy management
G06T2201/0065
Extraction of an embedded watermark Reliable detection
G06T2201/0081
whereby both original and watermarked images are required at decoder
G06T2201/0083
whereby only watermarked image required at decoder
G06T2201/0201
whereby only tamper or origin are detected and no embedding takes place
G06T2201/0202
whereby the quality of watermarked images is measured Measuring quality or performance of watermarking methods Balancing between quality and robustness
G06T2201/0203
whereby the image with embedded watermark is reverted to the original condition before embedding
G06T2201/0601
whereby calibration information is embedded in the watermark
