Wave-based non-line-of-sight computational imaging in Julia

An introduction to non-line-of-sight imaging, and how to create images of hidden objects around a corner in under 10 minutes!

Wave-based non-line-of-sight computational imaging in Julia launched on August 27, 2019 with 375 votes, #19 of 3,185 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 7 years on.

In plain words

This is a Julia-based computational imaging tool that uses wave-based methods to capture and reconstruct images around obstacles and around corners without direct line of sight. Launched in 2019, it enables researchers and engineers to visualize hidden or occluded scenes through non-traditional imaging techniques. The software is designed for users working in computer vision, imaging science, and physics applications who need advanced computational approaches to see beyond conventional camera limitations.

From the sources

Imagine being able to take a three dimensional image of a room without having to enter it. That seems like a rather unbelievable accomplishment, but it is slowing becoming a reality with the technologies being developed in computational imaging, particularly non-line-of-sight imaging. Even though compact, commercialized forms of the technology are still a ways off in the future, it is already possible to build a "camera" to collect the data with today’s technology. The process of capturing NLOS image data is fairly similar to taking regular image data, and while there are numerous variations of the approach, they all share the same components. First, there is an opening to the scene,…from analytech-solutions.com

  • A physically-based GPU ray tracer written in JuliaFeb 2026 · makie.org · ▲198

    We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo

  • Synthesize TikZ Graphics Programs for Scientific Figures and Sketches2024 · github.com · ▲132

    Creating high-quality scientific figures can be time-consuming and challenging, even though sketching ideas on paper is relatively easy. Furthermore, recreating existing figures that are not stored in formats preserving semantic information is equally complex. To tackle this problem, we introduce DeTikZify, a novel multimodal language model that automatically synthesizes scientific figures as semantics-preserving TikZ graphics programs based on sketches and existing figures. We also introduce a Monte Carlo Tree Search-based inference algorithm that enables DeTikZify to iteratively refine its…
