Abstract :
In this paper we propose an approach to carried object detection in short video sequences and overcome some of the shortcomings of other methods. The proposed approach can estimate pedestrian´s walking direction accurately without manual calibration and classify the probable carried object pixels with no need for prior information. Pedestrian´s silhouette is first aligned to get the temporal template. Then, the temporal template is matched against a set of exemplars using Principle Component Analysis (PCA) and exhaustive search. Finally, a fuzzy cluster method is applied to classify the protruding pixels. The method has been tested on PETS 2006 dataset and the detection of carried object is accurate and robust.
