A Robust Multi‐Oriented License Plate Detector and A Derived End‐to‐End License Plate Recognizer

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This is a research paper on license plate detection and recognition. A new center‐aware license plate detection and end‐to‐end license plate recognition framework is proposed for robust and efficient license plate detection and recognition under unconstrained scenarios.

Overviews of Optimization Techniques for Geometric Estimation [PDF]

, 2013
We summarize techniques for optimal geometric estimation from noisy observations for computer vision applications. We first discuss the interpretation of optimality and point out that geometric estimation is different from the standard statistical ...

Homography-Based Change Detection for Space-Based Satellite Inspection

, 2011
In order to maintain space situational awareness, it is necessary to maintain surveillance of objects in Earth orbit. A system of space-based imaging sensors could make much more detailed inspections of the existing resident space objects (RSOs). However,

Full Explicit Consistency Constraints in Uncalibrated Multiple Homography Estimation

, 2019
We reveal a complete set of constraints that need to be imposed on a set of 3×3 matrices to ensure that the matrices represent genuine homographies associated with multiple planes between two views.
