Human Motion Detection refers to the process of moving the human body in the input video images, including the position, scale, and posture, Human body tracking is the process of determining the human body correspondence between frames in a video image sequence. A series of processing methods such as low-pass filtering, background difference, morphological image processing, and Region connectivity analysis

Understanding object motion consists of two parts: recognition and modeling. Identify the objects of interest in the Zhennan customs of a previous frame in the subsequent frame of the Video Stream Search for corners Tracking feature points are called corner points. intuitively, corner points (rather than edges) A vertex that contains sufficient information and can be extracted from the current frame

1 -- Back Projection CamShift is a motion tracking algorithm called "Continuously Apative Mean-Shift. It is used to track the color information of moving objects in video images. I divide this algorithm into three parts for ease of understanding:1) Back Projection Calculation2) Mean Shift Algorithm3) CamShift AlgorithmFirst, we will discuss Back Projection, and then we will continue to discuss the next two

This week, I also learned about a new framework for 3D Motion Tracking. This framework uses random sampling and local optimization to achieve a better compromise between robustness and effectiveness, A local optimization method based on simulated human motion is introduced to improve the superiority of tracking. The fr

Tracking the ball's movements NoCodeConnect to the chipmunk simulator. Only after the corresponding method is extended can the position of the image be synchronously updated through chipmunk. This process can be implemented in multiple ways, such as storing a set of vertices to be checked. Fortunately, chipmunk has designed a very simple and abstract process for easy implementation. The following code is written once and rarely needs to be updated,
