The Vector-Gradient Hough Transform

—The paper presents a new transform, called Vector– Gradient Hough Transform, for identifying elongated shapes in grayscale images. This goal is achieved not only by collecting information on the edges of the objects, but also by reconstructing their transversal profile of luminosity. The main features of the new approach are related to its vector space formulation and the associated capability of exploiting all the vector information of the luminosity gradient.
