Sometimes milestones in the evolution of the DAGM Symposium become immediately visible. The Technical Committee decided to publish the symposium proceedings completely in English. As a consequence we successfully negotiated with Springer Verlag to publish in the international well accepted series “Lecture Notes in Computer Science”. The quality of the contributions convinced the editors and the lectors. Thanks to them and to the authors. We received 105 acceptable, good, and even excellent manuscripts. We selected carefully, using three reviewers for each anonymized paper, 58 talks and posters. Our 41 reviewers had a hard job evaluating and especially rejecting contributions. We are grateful for the time and effort they spent in this task. The program committee awarded prizes to the best papers. We are much obliged to the generous sponsors. We had three invited talks from outstanding colleagues, namely Bernhard Nebel (Robot Soccer – A Challenge for Cooperative Action and Perception), Thomas Lengauer (Computational Biology – An Interdisciplinary Challenge for Computational Pattern Recognition), and Nassir Navab (Medical and Industrial Augmented Reality: Challenges for Real Time Vision, Computer Graphics, and Mobile Computing). N. Navab even wrote a special paper for this conference, which is included in the proceedings. We were proud that we could convince well known experts to offer tutorials to our participants: H. P. Seidel, Univ. Saarbrücken – A Framework for the Acquisition, Processing, and Interactive Display of High Quality 3D Models; S. Heuel, Univ. Bonn – Projective Geometry for Grouping and Orientation Tasks; G. Rigoll, Univ.

The first project, frame_differencing.py, integrates motion detection within video sequences using a graphical user interface (GUI) facilitated by Tkinter, enhanced by image processing capabilities from OpenCV, and image handling using PIL. The core functionality, embedded in the FrameDifferencer class, organizes the application structure starting from initialization, which sets up the GUI layout with video control widgets, playback features, and filter selection. The script processes video frames to detect motion through grayscale conversion, Gaussian blurring, and frame differencing, highlighting motion by thresholding and contour detection. Enhanced interactivity is provided through real-time updates of motion detections on the GUI and user-enabled area selection for detailed analysis, including color histogram display. This flexible and extensible tool supports various applications from security surveillance to educational uses in image processing, embodying a practical approach to video analysis. The second project RunningGaussianAverage utilizes the running Gaussian average technique for motion detection within a graphical user interface (GUI) built on Tkinter. Upon initialization, it configures a master window and sets up video processing capabilities, including video stream handling, frame analysis, and displaying results on the GUI. The interface includes playback controls, a video display canvas, and a listbox for motion event notifications, allowing interactive management of video analysis. Core functionalities like video loading, playback control, and frame processing leverage the imageio and OpenCV libraries to handle video input and perform real-time image processing tasks such as blurring, grayscale conversion, and motion detection through frame differencing. The application is structured to provide an intuitive platform for users to engage with motion detection technology effectively, showcasing changes directly within the GUI. The third project introduces a sophisticated application that utilizes the Mixture of Gaussians (MOG) method for motion detection within a user-friendly Tkinter-based GUI. Leveraging OpenCV's cv2.createBackgroundSubtractorMOG2(), the application excels in background modeling and foreground detection, effectively handling various lighting conditions and shadow detection, making it ideal for security and surveillance applications. The GUI is designed to enhance user interaction, featuring video display, playback controls, adjustable detection settings, and dynamic results display through list boxes and scrollbars. It also offers advanced filtering options like Gaussian and median blurs, along with more complex filters such as wavelet transforms and anisotropic diffusion, all adjustable via the GUI. This setup allows for real-time frame processing, detection visualization, and interactive exploration, making it a potent tool for educational purposes, professional security setups, and enthusiasts in video processing technology. The fourth project develops a sophisticated motion detection system using Kernel Density Estimation (KDE), integrated into a Tkinter-based graphical interface, simplifying the advanced image processing for users without deep technical expertise. Central to this application is the use of OpenCV's MOG2 background subtractor which excels in differentiating foreground activity from the background, especially in varied lighting and shadow conditions, thus enhancing robustness in diverse environments. The GUI is intuitively designed, featuring video playback controls and real-time video frame rendering along with a motion density map that accumulates and visualizes movement patterns over time. The application processes video frames by applying Gaussian blurring to reduce noise and then uses the MOG2 model to create a foreground mask, refined further to delineate motion clearly. This setup allows for precise contour detection to identify and mark moving objects, providing detailed motion event analysis directly on the interface. This project effectively marries complex image processing capabilities with a user-friendly interface, making sophisticated motion detection technology accessible for surveillance, research, and broader applications. The fifth project develops an advanced motion detection system using the K-Nearest Neighbors (KNN) algorithm for effective background subtraction, all within a user-friendly Tkinter-based graphical interface, ideal for surveillance and monitoring applications. The KNN background subtractor stands out for its dynamic adaptation, enhancing detection accuracy under varying lighting conditions while minimizing false positives from environmental changes. Users interact through a thoughtfully designed GUI, featuring real-time video playback, motion event logs, and intuitive controls like play, pause, and frame navigation. Additionally, the system includes various filters such as Gaussian blur and wavelet transforms to optimize detection quality. Detected motions are highlighted with bounding boxes and detailed in a sidebar, simplifying the tracking process. Advanced features like zoom and area-specific analysis further augment the tool's utility, making it versatile for applications ranging from security surveillance to traffic monitoring, all the while maintaining ease of use and robust analytical capabilities. The sixth project, "Median Filtering with Filtering", develops a sophisticated motion detection application using Python, integrating Tkinter for the GUI, OpenCV for image processing, and ImageIO for video management. This application utilizes median filtering to effectively reduce noise in video frames, enhancing motion detection capabilities for security surveillance, wildlife monitoring, and other applications requiring movement tracking. The GUI is intuitively designed with video playback controls, adjustable motion detection sensitivity, and a log of detected movements, making it highly interactive and user-friendly. Users can also apply various filters like Gaussian and bilateral smoothing to improve image quality under different conditions. The application is built with expandability in mind, allowing for easy integration of additional filters, enhanced algorithms, or more sophisticated functionalities to meet specific user needs or to be incorporated into larger systems.
