Yes, I understand why the initial compression of a bitmap (not necessarily a .BMP) to a JPEG is lossy, via the quantization step after DCT. But if I decompress a JPEG back to a new bitmap, and then re ...

PythoC lets you use Python as a C code generator, but with more features and flexibility than Cython provides. Here’s a first look at the new C code generator for Python. Python and C share more than ...

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 ...

This project presents an advanced image compression system designed to enhance the standard JPEG algorithm by introducing a more perceptually-driven approach. The traditional JPEG standard relies on a ...

Would you trust an AI agent to run unverified code on your system? For developers and AI practitioners, this question isn’t just hypothetical—it’s a critical challenge. The risks of executing ...

Concerns about the risks posed by tampered images have been showing up regularly in the research over the past couple of years, particularly in light of a new surge of AI-based image-editing ...

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 ...

Serving tens of millions of developers, Microsoft's dev team for Python in Visual Studio Code shipped a new release with three major new features, including a "full" language server mode for Pylance, ...

A new research paper from Canada has proposed a framework that deliberately introduces JPEG compression into the training scheme of a neural network, and manages to obtain better results – and better ...

A known Chinese advanced persistent threat (APT) group known as Mustang Panda is the likely culprit behind a sophisticated, ongoing cyber-espionage campaign. It starts with a malicious email, and ...
