14 p, 1.0 MB Cross-spectral local descriptors via quadruplet network / Aguilera, Cristhian A (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Toledo Morales, Ricardo (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Sappa, Angel Domingo (Centre de Visió per Computador (Bellaterra, Catalunya)) ; Aguilera, Cristhian A (Universidad del Bío-Bío (Concepción, Xile))
This paper presents a novel CNN-based architecture, referred to as Q-Net, to learn local feature descriptors that are useful for matching image patches from two different spectral bands. Given correctly matched and non-matching cross-spectral image pairs, a quadruplet network is trained to map input image patches to a common Euclidean space, regardless of the input spectral band.

20 p, 8.2 MB Taking Advantage of Selective Change Driven Processing for 3D Scanning / Vegara, Francisco (Universitat de València. Departament d'Informàtica) ; Boluda, Jose A. (Universitat de València. Departament d'Informàtica) ; Pardo, Fernando (Universitat de València. Departament d'Informàtica) ; Zuccarello, Pedro (Institut de Microelectrònica de Barcelona)
This article deals with the application of the principles of SCD (Selective Change Driven) vision to 3D laser scanning. Two experimental sets have been implemented: one with a classical CMOS (Complementary Metal-Oxide Semiconductor) sensor, and the other one with a recently developed CMOS SCD sensor for comparative purposes, both using the technique known as Active Triangulation.
