  • 摘要:Recently, real-time object detection systems have become a major challenge in the smart vehicle. In this work, we aim to increase both pedestrian and driver safety through improving their recognition rate in the vehicle’s embedded vision systems. Based on the Histogram of Oriented Gradients (HOG) descriptor, an optimized object detection system is presented in order to achieve an efficient recognition system for several obstacles. The main idea is to customize the weight of each bin in the HOG-feature vector according to its contribution in the description process of the extracted relevant features. Performance studies using a linear SVM classifier prove the efficiency of our approach. Indeed, based on the INRIA datasets, we have improved the sensitivity rate of the pedestrian detection by 11% and the vehicle detection by 5%.
