Image authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

متن کاملLearned Perceptual Image Enhancement
Learning a typical image enhancement pipeline involves minimization of a loss function between enhanced and reference images. While L1 and L2 losses are perhaps the most widely used functions for this purpose, they do not necessarily lead to perceptually compelling results. In this paper, we show that adding a learned no-reference image quality metric to the loss can significantly improve enhan...
متن کاملPerceptual Image Hashing
With the fast advancement of computer, multimedia and network technologies, the amount of multimedia information that is conveyed, broadcast or browsed via digital devices has grown exponentially. Simultaneously, digital forgery and unauthorized use have reached a significant level that makes multimedia authentication and security very challenging and demanding. The ability to detect changes in...
متن کاملPerceptual Image Enhancement
Enhancing image quality has become an important issue as the volume of digital images increases exponentially and the expectation of high-quality images grows insatiably. Digitized images commonly suffer from poor visual quality due to distortions, low contrast, the deficiency of lighting, defocusing, atmospheric influences such as fog, severe compression, and transmission errors. Hence, image ...
