- Detección y Agrupación de Logos Luis Miguel Prócel Vicent Casellas Multidisciplinaria (Ciencias Naturales y Exactas) SIFT descriptor Logo detection and grouping Geometric Hashing algorithm In this paper we develop an algorithm for logo detection and grouping in images. For logo detection, the“Scale-Invariant Feature Transform” (SIFT) descriptor is used, which is one of the most studied and used in pattern recognition in the fields of image analysis and computer vision. We have developed a geometric algorithm for grouping and counting the detected logos. This algorithm is based on the so-called “Geometric Hashing” algorithm. Finally, we perform some tests in order to analyze the robustness of the algorithm. 2012 artículo científico 1390-5384 https://www.redalyc.org/articulo.oa?id=726180827012 es http://www.redalyc.org/revista.oa?id=7261 Avances en Ciencias e Ingenierías application/pdf Universidad San Francisco de Quito Avances en Ciencias e Ingenierías (Ecuador) Num.1 Vol.4
