Reconnaissance de zones de texte et suivi d'objets dans les images et les vidéos Text recognition and 2D/3D object tracking by
Rodrigo Minetto(
Book
)
1 edition published in 2012 in English and held by 1 WorldCat member library worldwide
In this thesis we address three computer vision problems: (1) the detection and recognition of flat text objects in images of real scenes; (2) the tracking of such text objects in a digital video; and (3) the tracking an arbitrary threedimensional rigid object with known markings in a digital video. For each problem we developed innovative algorithms, which are at least as accurate and robust as other stateoftheart algorithms. Specifically, for text recognition we developed (and extensively evaluated) a new HOGbased descriptor specialized for Roman script, which we call THOG, and showed its value as a postfilter for an existing text detector (SnooperText). We also improved the SnooperText algorithm by using the multiscale technique to handle widely different letter sizes while limiting the sensitivity of the algorithm to various artifacts. For text tracking, we describe four basic ways of combining a text detector and a text tracker, and we developed a specific tracker based on a particlefilter which exploits the THOG recognizer. For rigid object tracking we developed a new accurate and robust algorithm (AFFTrack) that combines the KLT feature tracker with an improved camera calibration procedure. We extensively tested our algorithms on several benchmarks wellknown in the literature. We also created benchmarks (publicly available) for the evaluation of text detection and tracking and rigid object tracking algorithms
