[The aim of image analysis is to extract useful information from digital images. The fundamental problem lies in how to combine the information from multiple measurements, the pixel values, into a coherent interpretation. This work discusses a very reduced version of this general problem, namely...
[At the turn of the century, Desolneux, Moisan, and Morel undertook the task of formalizing the Gestalt theory into a mathematical framework [19, 22]. The motivation for this ambitious project was to provide a foundation for computer vision based, like the Gestalt theory [46, 51, 61, 62], on a...
[This chapter describes in full detail the LSD algorithm [31, 35, 36] for line segment detection. It is based on the a contrario framework described in the previous chapter, but instead of searching exhaustively for line segments, it uses the heuristic search plus validation approach, resulting...
[This chapter presents some experiments to illustrate the behavior of the a contrario line segment detector, indicating the good properties as well as its shortcomings. The results are compared with some existing approaches, concluding with an empirical evaluation of the algorithm computational...
[No existing algorithm for line segment detection can be said to perform this task to full satisfaction. The problem is indeed ill-posed: people often disagree about the exact set of line segments that corresponds to a particular image, revealing differences in the basic notion or in the...
