综合表观和运动模式的视频轮椅检测方法
A novel wheelchair video detection method based on a combined appearance and motion pattern
摘要
Abstract
This paper proposes a novel method to detect wheelchairs in video using the combination of appearance and motion pattern. An appearance based detector is used to detect objects frame by frame, where a cascaded detector is designed using the Haar-like feature and the HOG (histograms of oriented gradients) feature. A motion based classifier is proposed further to distinguish appearance-similar wheelchairs and pedestrians, which usually impedes performance of appearance based detectors. The accuracy and the efficiency of the proposed method were validated by extensive experiments.关键词
