Pedestrian Detection Fusing HOG Based on LE and Haar-Like Feature
In order to change the low detecting speed and excess redundant information of the gradient histogram (HOG), this paper proposes the pedestrian detection fusing HOG based on Laplacian Eigenmaps (LE) dimensionality reduction and Haar-Like feature. By constructing a pedestrian detection sample set mixed with HOG and Haar-Like feature set, and using LE to reduce the HOG feature, then fuse Haar-Like feature extraction with HOG-LE feature. Finally, we use Adaboost cascade strong classifier to test INRIA Person sample library, the test results are obviously better than the single feature extraction method in terms of detection rate, and the text also compares the method with some other pedestrian detection methods. The pedestrian detection fusing HOG based on LE reduced dimension and Haar-Like features proposed in this paper improves detection rate effectively in real scenarios.
