資源簡介

博文:基于python的行人與車輛檢測和跟蹤實現(HOG+SVM/HAAR) 鏈接:https://blog.csdn.net/qq_38523834/article/details/89619697 文件里面有我提到的視頻,cars.xml文件和myhaar.xml文件。需要的Python庫在requirements.txt有提及: cmake==3.12.0 dlib==19.16.0 numpy==1.15.3 opencv-python==3.4.3.18 這些是最低版本,可以比這個高。我是用python3.6運行的。 沒有安裝dlib庫的同學,注意在安裝好所需庫之后,需要自行下載一個.whl文件后才能用pip install dlib 安裝成功哦。 相關下載鏈接在這個博文里:https://blog.csdn.net/wzx479/article/details/79890440
