Title
Fuzzy Perceptual Watermarking For Ownership Verification
Abstract
An adaptive watermarking method based on the human visual system model and the fuzzy inference system in wavelet domain is proposed. Fuzzy logic is used for data fusion and builds a HVS model for spatial masking in wavelet domain. Modeling spatial masking is a complicated task and there is no single theoretical formulation to precisely compute the perceptual value for a corresponding wavelet coefficient. Fuzzy logic is used for data fusion and operates on the HVS model for spatial masking in wavelet domain. The fuzzy input variables (brightness, luminosity, texture) are computed for each wavelet coefficient in the image. The output of the fuzzy system is a single value which gives a perceptual value for each corresponding wavelet coefficient. The fuzzy based watermarks are robust to attacks and at the same time achieve a high level of imperceptibility.
