Abstract
A new flashlight scene detection approach is presented. It focuses on two techniques: a new flashlight model based on the spatial-temporal characteristics of intensity value for the DC sequence, and a local threshold selection scheme using the sliding window. The advantages of this approach are its good performance for multi-frame and gradual flashlight scene cases, and local threshold selection. Experimental results show that the proposed algorithm is fast, robust and high accuracy
