Float Cascade Method for Pedestrian Detection
A novel pedestrian detection method based on the Four Direction Features (FDF), called FloatCascade pedestrian detection, is proposed for the pedestrian detection problem, which can be applied to the pedestrian detection problem in a single image. The FDF can represent pedestrian well, and the computation cost is lower than the HOG’s. FloatCascade applies the plus-l-minus-r method to select the effective cascade features to improve the detection performance, where l is fixed by experience, r is a float value which must be lower than l or quite to l. whether add features or not is decided by the detection rate, while whether subtract features or not is decided by error rate. Experimental results show that the MutualCascade method is more effective than Voila and Jones’ cascade and some other Adaboost-based method, and is comparable with HOG-based methods. It also demonstrates a higher performance compared with the state-of-the-art methods.
