Digital watermarking robust to geometric distortions.

In this paper, we present two watermarking approaches that are robust to geometric distortions. The first approach is based on image normalization, in which both watermark embedding and extraction are carried out with respect to an image normalized to meet a set of predefined moment criteria. We propose a new normalization procedure, which is invariant to affine transform attacks. The resulting watermarking scheme is suitable for public watermarking applications, where the original image is not available for watermark extraction. The second approach is based on a watermark resynchronization scheme aimed to alleviate the effects of random bending attacks. In this scheme, a deformable mesh is used to correct the distortion caused by the attack. The watermark is then extracted from the corrected image. In contrast to the first scheme, the latter is suitable for private watermarking applications, where the original image is necessary for watermark detection. In both schemes, we employ a direct-sequence code division multiple access approach to embed a multibit watermark in the discrete cosine transform domain of the image. Numerical experiments demonstrate that the proposed watermarking schemes are robust to a wide range of geometric attacks.

New Additive Watermark Detectors Based On A Hierarchical Spatially Adaptive Image Model

In this paper, we propose a new family of watermark detectors for additive watermarks in digital images. These detectors are based on a recently proposed hierarchical, two-level image model, which was found to be beneficial for image recovery problems. The top level of this model is defined to exploit the spatially varying local statistics of the image, while the bottom level is used to characterize the image variations along two principal directions. Based on this model, we derive a class of detectors for the additive watermark detection problem, which include a generalized likelihood ratio, Bayesian, and Rao test detectors. We also propose methods to estimate the necessary parameters for these detectors. Our numerical experiments demonstrate that these new detectors can lead to superior performance to several state-of-the-art detectors.

船用残渣型燃料油脱硫技术进展

随着2020年国际海事组织（International Maritime Organization,IMO）船用燃料油限硫政策的施行,船用残渣型燃料油的脱硫技术受到了业界的较大关注。重质原料油是船用残渣型燃料油的主要组成部分,重质原料油脱硫技术分为加氢技术和非加氢技术。加氢技术主要有固定床、沸腾床（膨胀床）、悬浮床（浆态床）及移动床等。非加氢技术主要有碱金属化合物脱硫、选择性氧化⁃萃取/热解/过程强化脱硫、电化学脱硫、生物脱硫及钠法脱硫等。加氢脱硫技术中,固定床加氢技术更适合现阶段生产硫质量分数≤0.5%的船用残渣型燃料油,若要生产硫质量分数≤0.1%的船用残渣型燃料油,则需要控制原料油中硫质量分数或进行油品调和。非加氢脱硫技术中,选择性氧化⁃超声辅助及钠法脱硫技术均可直接生产硫质量分数≤0.1%的重质原料油,但钠法脱硫技术具有更好的应用前景。
