We present Ego-1K, a large-scale collection of time-synchronized egocentric multiview videos designed to advance neural 3D video synthesis and dynamic scene understanding. The dataset contains nearly 1,000 short egocentric videos captured with a custom rig with 12 synchronized cameras surrounding a 4-camera VR headset worn by the user. Scene content focuses on hand motions and hand-object interactions in different settings. We describe rig design, data processing, and calibration. Our dataset enables new ways to benchmark egocentric scene reconstruction methods, an important research area as smart glasses with multiple cameras become omnipresent. Our experiments demonstrate that our dataset presents unique challenges for existing 3D and 4D novel view synthesis methods due to large disparities and image motion caused by close dynamic objects and rig egomotion. Our dataset supports future research in this challenging domain. It is available at https://huggingface.co/datasets/facebook/ego-1k.

The aim of this book is to introduce the language XMF. This is done by defining the language, providing some examples of applications that can be written directly in the XOCL language that comes with XMF, and then by showing how XMF can be used for language engineering. The main focus of this book is on language engineering by example.

Modern day system developers have some serious problems to contend with. The systems they develop are becoming increasingly complex as customers demand richer functionality delivered in ever shorter timescales. They have to manage a huge diversity of implementation technologies, design techniques and development processes: everything from scripting languages to web-services to the latest 'silver bullet' design abstraction. To add to that, nothing stays still: today's 'must have' technology rapidly becomes tomorrow's legacy problem that must be managed along with everything else. How can these problems be dealt with? In this book we propose that there is a common foundation to their resolution: languages. Languages are the primary way in which system developers communicate, design and implement systems. Languages provide abstractions that can encapsulate complexity, embrace the diversity of technologies and design abstractions, and unite modern and legacy systems.
