在检测任务中,训练数据集的标签里会给出目标物体真实边界框所对应的$(x_1, y_1, x_2, y_2)$,这样的边界框也被称为真实框(ground truth box),图1画出了3个人像所对应的真实框。模型会对目标物体可能出现的位置进行预测,由模型预测出的边界框则称为预测框(prediction box)。 要完成一项检测任务,我们通常...

You can scale the bounding boxes yourself in the probe function. But you need to attach that to the gstbuffer, therwise the rest of the processing in the pipeline is still processing the data in the gstbuffer. We do not currently have a demonstration of this type of processing in python....
