WebFeb 10, 2024 · Note how the bounding box increases and decreases in size as the envelope goes closer and further away from the camera. It also rotates along with envelope and even compresses when is turned on its side. Conclusions. The mean shift and cam shift algorithms are both incredibly useful and powerful tools to use in object tracking. Web作者您好我是用的之前自己训练的yolov7-e6e.pt这个模型来做的tracking，但是我发现对同一个视频做tracking和detection得到的结果差距很大，detection可以检测出一些物体但是在 tracking的过程中就检测不出来，同样在tracking过程中bounding box的晃动幅度会比detection大很多，请问这些情况是正常的吗 collins road theater free movies 2019
