The first project, the GUI motion analysis tool gui_motion_analysis_fsbm.py, employs the Full Search Block Matching (FSBM) algorithm to analyze motion in videos. It imports essential libraries like tkinter, PIL, imageio, cv2, and numpy for GUI creation, image manipulation, video reading, computer vision tasks, and numerical computations.
The script organizes its functionalities within the VideoFSBMOpticalFlow class, managing GUI elements through methods like create_widgets() for layout management, open_video() for video selection, and toggle_play_pause() for video playback control. It employs the FSBM algorithm for optical flow estimation, utilizing methods like full_search_block_matching() for motion vector calculation and show_optical_flow() for displaying motion patterns. Ultimately, by combining user-friendly controls with powerful analytical capabilities, the script facilitates efficient motion analysis in videos.
The second project gui_motion_analysis_fsbm_dsa.py aims to provide a comprehensive solution for optical flow analysis through a user-friendly graphical interface. Leveraging the Full Search Block Matching (FSBM) algorithm with the Diamond Search Algorithm (DSA) optimization, it enables users to estimate motion patterns within video sequences efficiently. By integrating these algorithms into a GUI environment built with Tkinter, the script facilitates intuitive exploration and analysis of motion dynamics in various applications such as object tracking, video compression, and robotics.
Key features include video file input, playback control, parameter adjustment, zooming capabilities, and optical flow visualization. Users can interactively analyze videos frame by frame, adjust algorithm parameters to tailor performance, and zoom in on specific regions of interest for detailed examination. Error handling mechanisms ensure robustness, while support for multiple instances enables simultaneous analysis of multiple videos.
