Object detection is a computer vision technique for locating instances of objects in images or videos. Object detection algorithms typically leverage machine learning or deep learning to produc
The Architecture. Our detection network has 24 convolutional layers followed by 2 fully connected layers. Alternating 1 × 1 convolutional layers reduce the features space from preceding layers. We pretrain the convolutional layers on the ImageNet classification task at half the resolution (224 × 22...
YOLO之前的Object Detection方法主要是通过Region Proposal产生大量的Bounding Box,再用Classifier判断每个Bounding Box是否包含Object,以及Object所属类别的Probability。 YOLO提出了一种新的Object Detection方法,它将Object Detection作为一个空间分离的Bounding Box和对应Class Probability的Regression问题来处理。YOLO使用单个神经...
Performance metrics for object detection are quantitative measures used to assess how accurate the algorithm works in computer vision. More specifically, these metrics evaluate the accuracy of detecting, locating, and classifying objects within an image or a video frame. This way, object detection eval...
