Drawing Red Rectangular Markers at Specified Positions on Images

This program facilitates object marking by drawing red rectangular boxes at specified positions on images, thereby simplifying tracking procedures. This function is highly valuable for object tracking scenarios, allowing users to quickly and accurately select targets for tracking. During tracking operations, users can easily adjust the rectangle's position and size to accommodate varying target characteristics. The implementation typically involves image coordinate system handling, where the rectangle's parameters (x, y, width, height) are defined using pixel coordinates, with OpenCV's cv2.rectangle() function commonly employed for rendering. Additionally, the program incorporates supplementary features such as automatic target detection using algorithms like Haar cascades or YOLO, real-time tracking through correlation filters or deep learning models, and trajectory visualization via path plotting functions. These integrated capabilities provide users with enhanced convenience for object tracking tasks while delivering more precise and comprehensive tracking outcomes through systematic coordinate management and visual feedback mechanisms.
