Semi-fragile watermark for color image tamper detection and recovery. Robust after JPEG and normal processing, fragile when content is tampered. Code in Matlab.

Abstract: Efficiency and security issues are significant considerations in the transmission of information. The joint compression and encryption method is an effective way to improve both issues. In ...

In today's world of AI and machine intelligence, it sometimes skips the mind that the primary end-user of many computing systems are … human. And, as humans, we are far from perfect – not just in our ...

In this tutorial, we explore how we can seamlessly run MATLAB-style code inside Python by connecting Octave with the oct2py library. We set up the environment on Google Colab, exchange data between ...

Compression is a cornerstone of computational intelligence, deeply rooted in the theory of Kolmogorov complexity, which defines the minimal program needed to reproduce a given sequence. Unlike ...

Microsoft has quietly rolled out support for the JPEG XL image format in the latest Windows 11 24H2 update. This new feature, available through an extension in the Microsoft Store, promises to enhance ...
