More On Motion Estimation

5 Point Algorithm, How to solve DLT, and 8 point algorithm

Why Do We Still Need Multi-View Geometry, In 2024? LLMs are everywhere now. However, they are rarely seen in 3D scene reconstruction except for those on depth learning from single images. Dong et ...

Motion Estimation From Epipolar Constraints

This is an Introduction of Epipolar Constraints and 2D-2D Motion Estimation

Intro This blog is inspired by this great great book: 14 Lectures in Visual SLAM, authored by Dr. Gao Xiang et al. This article will walk you through 8-point algorithm when features lie on differe...

Copying Docker Images to Another Machine

local registry + SSH reverse tunnel

Why Not docker save? docker save can deadlock or hang when the image is stored in the containerd image store (shows 0B in docker images). This is caused by futex contention in Go’s goroutine-based...

Dockerd and Linux Futex

How Docker uses containerd, and how Linux futex works

Containerd containerd is the low-level container runtime that Docker uses under the hood. It manages image storage, pulling images, unpacking layers, and container lifecycle. For example, docker p...
