Object Detection Model Support (Lite)
Object dectectin introduction
Object detection can identify the object in the image and its position in the image. For the following figure, the output of the object detection model is shown in the following table. The rectangular box is used to identify the position of the object in the graph and the probability of the object category is marked. The four numbers in the coordinates are Xmin, Ymin, Xmax, Ymax; the probability represents the probility of the detected object.
