Watermarking, the practice of embedding imperceptible information into media such as images, videos, audio, and text, is essential for intellectual property protection, content provenance and attribution. The growing complexity of digital ecosystems necessitates watermarks for different uses to be embedded in the same media. However, to detect and decode all watermarks, they need to coexist well with one another. We perform the first study of coexistence of deep image watermarking methods and, contrary to intuition, we find that various open-source watermarks can coexist with only minor impacts on image quality and decoding robustness. The coexistence of watermarks also opens the avenue for ensembling watermarking methods. We show how ensembling can increase the overall message capacity and enable new trade-offs between capacity, accuracy, robustness and image quality, without needing to retrain the base models.

Honda is officially introducing two Series 0 electric vehicle prototypes at CES next year, and the company says they'll be available for purchase around the world sometime in 2026. The vehicles will be based on the futuristic-looking concepts the company presented at CES 2024, including a flagship model called the Saloon that featured an aerodynamic design. They'll be the company's first entries in the Series 0 lineup, which are also expected to feature an advanced driver-assisted system and, over the coming years, AI-powered automated driving features. In addition to presenting the prototypes themselves, Honda will also introduce a new proprietary vehicle operating system that the Series 0 cars will use. Plus, it will give you a look at the SoC powering the vehicles during the event. Honda trailed behind competitors in terms of making the transition to electric vehicles, but its first electric SUV, the Prologue, became one of the best-selling EVs in the US after its release in the country earlier this year.
