Abstract:

To improve detection rate of pedestrian detection system, a novel pedestrian detection model by combining the Gaussian mixture background model and histograms of oriented gradients (HOG) plus support vector machine (SVM) is proposed. First, foreground segmentation is done using the Gaussian mixture model (GMM) to extract moving target areas. In the recognition of pedestrians, the dimension of the HOG descriptor is reduced by resizing the size of the detecting window. In addition, an error recognition region is used to re-update the information of sample dataset to optimize the SVM classifier. Performance of this model is evaluated with the test frames randomly chosen from a video taken in a realistic scene. The results indicate that GMM and HOG+SVM can ensure accuracy and speed of detection, and limit false detection rate to 4 %. Real-time and accurate pedestrian detection in complex scenes are achieved.

Key words: pedestrian detection, Gaussian mixture model (GMM), region extraction, histogram of oriented gradient (HOG), dimension reduction
