Source: Progressively Optimized Local Radiance Fields for Robust View Synthesis

Summary
This research presents a new algorithm that uses a single casually captured video to reconstruct the radiance field of a large-scale scene. They overcome the challenges of inaccurate camera poses and finite representational capacity through progressive optimization with dynamically allocated local radiance fields. Their approach outperforms the state-of-the-art on evaluation datasets and achieves smoother stabilization than 2D methods.

Fact

📹 The algorithm reconstructs the radiance field of a large-scale scene from a single casually captured video.

🔄 They use progressive optimization for improved robustness by jointly estimating camera poses and radiance field in a progressive manner.

🔎 They overcome the challenge of finite representational capacity through dynamically allocated local radiance fields trained with frames within a temporal window.

🌳 Their approach outperforms the state-of-the-art on evaluation datasets, including Tanks and Temples and their collected outdoor dataset, Static Hikes.

🚶‍♂️ Their approach achieves smoother stabilization than 2D methods such as FuSta.

Summary
The Iskra EMZ1001, also known as the S2000, was co-developed by the Faculty of Electrical Engineering of the University of Ljubljana and AMI, but it was mainly produced by AMI. It is a basic control-oriented processor that was designed to run industrial automation, games, and other devices. Although it has a core 4-bit ALU, it interfaces to the outside world with an 8-bit databus and has a 13-bit address bus. It also includes timers, second counting, and interfaces for buttons and LEDs.

Facts

💾 Iskra’s EMZ1001, also known as the S2000, was co-developed by the Faculty of Electrical Engineering of the University of Ljubljana and AMI, and it was created to enable the indigenous production of processors in Yugoslovia.

🔌 The processor is a basic control-oriented processor, which is equipped to run machines for industrial automation, games, toaster ovens, etc.

🧮 The Iskra EMZ1001 interfaces to the outside world with an 8-bit databus, but it features a core 4-bit ALU, and has both 4-bit and 8-bit buses internally.

🔋 The processor operates on a single 9V power supply, making it viable to operate off of a 9V battery.

📝 The S2000/EMZ1001 instruction set consists of 51 single-byte instructions.

💾 The processor contains a stack, enabling subroutines and interrupts to be handled easily.
