A Contrario Line Segment Detection
The reliable detection of low-level image structures is an old and still challenging problem in computer vision. This book leads a detailed tour through the LSD algorithm, a line segment detector designed to be fully automatic. Based on the a contrar

Preface
Among the myriad algorithms and techniques that constitute the field of computer vision, this work focuses on just one: the LSD algorithm for line segment detection in digital images. The interest in this algorithm is twofold: First, due to its relative simplicity, the method can be understood in full detail and provides a complete example of a low-level image analysis algorithm. Second, the method is based on the a contrario approach and it illustrates well the kind of parameterless al
