目标检测 (Object Detection) 就是将图片中的物体用一个个矩形框框出来,并且识别出每个框中的物体是啥,而且最好的话是能够将图片的所有物体都框出来。 目标检测本质上包含两个任务:物体识别和物体定位。 在本文中,我们将使用 OpenCV(一种流行的计算机视觉库)构建一个对象检测和跟踪系统。 OpenCV 具有许多功能,深度学习也不例外。 从
我们将使用 OpenCV 的 detectMultiScale() 函数来识别大符号和小符号: # Use minSize because for not# bothering with extra-small# dots that would look like STOP signsfound=stop_data.detectMultiScale(img_gray,minSize=(20,20))# Don't do anything if there's# no signamount_found=len(found)ifam...
