摘要： PURPOSE: A pedestrian detection method of a pedestrian detection device is provided to perform pedestrian detection on a search window using a second classifier with high accuracy after reducing the number of search windows, thereby performing highly accurate detection of an object while reducing the complexity of detection procedure and power consumption. CONSTITUTION: A pedestrian detection device obtains an image from a digital image device and performs blocking of search windows(210,220). The pedestrian detection device selects a specific block from blocks determined by a pre-learned classifier(230) and produces a specific vector of HOG features from the selected block(240,250). The pedestrian detection device calculates a SVM(Support Vector Machine) response value using the produced feature vector, and performs a first object detection by applying the response value to an AdaBoost Classifier(260,270). If a pedestrian is detected at the first object detection, the pedestrian detection device performs a second object detection to the search window(280).
