Abstract
A system () for detecting whether an image () is blurred performs the steps of: identifying valid light trails in the test image (), and classifying the test image as blurred if there is a sufficient number of matching valid light trails oriented in a repetitive pattern (). The system () is designed to automatically detect whether a night scene image () is blurred based on the existence and characteristics of any light trails () in the captured image (). Because the method extracts the characteristics of the light trails () and analyzes these light trails (), it accurately detects blur in the challenging night scene images and has a relatively low false positive rate.
