The paper "Visual Tracking: An Experimental Survey" by Smeulders et al. (2014) provides a comprehensive evaluation of visual tracking algorithms, aiming to assess their performance in a wide range of realistic scenarios. The authors selected 19 trackers from various sources, including those cited frequently in the literature and recent submissions to major conferences, and evaluated them on 315 video fragments covering a diverse set of conditions such as illumination changes, occlusions, clutter, and camera motion. The evaluation metrics used include survival curves, Kaplan-Meier statistics, Grubbs testing, and the F-score, which are shown to be effective in comparing the trackers' performance. The study highlights that the top-performing trackers do not share a common underlying method, and their effectiveness is maintained across different types of trackers. The paper also discusses the strengths and weaknesses of various tracking paradigms, including those based on matching, extended appearance models, constraints, and discriminative classification. The analysis is structured around five components: target region representation, appearance representation, motion model, background representation, and scene information, providing a detailed decomposition of the tracking process.The paper "Visual Tracking: An Experimental Survey" by Smeulders et al.
