There are many choices for graduation design based on matlab, but no matter what you do, the parameters based on MATLAB must be accurate, otherwise the whole program will not be built.

Suggested topic: Early warning against falling of moving targets based on MATLAB. Implementation content: design GUI interface and input dynamic video. Considering that the camera can be fixed, the background is generally fixed. Taking the first frame of video as the background frame, the video frame is extracted, and each frame is compared with the background frame to get the moving foreground. Converted into a binary image, the frame is circumscribed by a rectangle, and the centroid of the moving object is obtained. According to the change of the center of mass of the previous frame and the length-width ratio of the bounding rectangle, we can judge human behavior, such as walking, standing, reaching out and falling. If a fall is detected, a voice alarm and a text prompt will be issued.
