RST-Invariant Semi-fragile Image Authentication Based on DWT-Coefficient Quantization
Abstract. In this paper, we propose an image moment-based geometric normalization to be applied before embedding and extracting a digital watermark in the DWT-domain of JPEG2000. A...

Linearization of Mammograms Using Parameters Derived from Noise Characteristics
A method is proposed for converting digitized mammograms to a normalized representation, in which pixel values are linearly related to the logarithm of x-ray exposure. This method ...
