Omnidirectional Depth Computation from a Single Image

Omnidirectional cameras offer a much wider field of view than the perspective ones and alleviate the problems due to occlusions. However, both types of cameras suffer from the lack of depth perception. A practical method for obtaining depth in computer vision is to project a known structured light pattern on the scene avoiding the problems and costs involved by stereo vision. This paper is focused on the idea of combining omnidirectional vision and structured light with the aim to provide 3D information about the scene. The resulting sensor is formed by a single catadioptric camera and an omnidirectional light projector. It is also discussed how this sensor can be used in robot navigation applications

Plane-to-plane positioning from image-based visual servoing and structured light

In this paper we face the problem of positioning a camera attached to the end-effector of a robotic manipulator so that it gets parallel to a planar object. Such problem has been treated for a long time in visual servoing. Our approach is based on linking to the camera several laser pointers so that its configuration is aimed to produce a suitable set of visual features. The aim of using structured light is not only for easing the image processing and to allow low-textured objects to be treated, but also for producing a control scheme with nice properties like decoupling, stability, well conditioning and good camera trajectory

Internet for Image Searching

"Internet for Image Searching" is a free online tutorial to help staff and students in universities and colleges to find digital images for their learning and teaching. The emphasis of the tutorial is on finding copyright cleared images which are available free; facilitating quick, hassle-free access to a vast range of online photographs and other visual resources. "This tutorial is an excellent resource for anyone needing to know more about where and how to find images online. The fact that it concentrates on copyright cleared images will make it even more valuable for busy learning and teaching professionals, researchers and students alike. It will also serve to inspire confidence in those needing to use images from the web in their work." (Sharon Waller of the Higher Education Academy).

El problema de Alhacén

El presente documento es un estudio detallado del problema conocido bajo el título de Problema de Alhacén. Este problema fue formulado en el siglo X por el filósofo y matemático árabe conocido en occidente bajo el nombre de Alhacén. El documento hace una breve presentación del filósofo y una breve reseña de su trascendental tratado de óptica Kitab al-Manazir. A continuación el documento se detiene a estudiar cuidadosamente los lemas requeridos para enfrentar el problema y se presentan las soluciones para el caso de los espejos esféricos (convexos y cóncavos), cilíndricos y cónicos. También se ofrece una conjetura que habría de explicar la lógica del descubrimiento implícita en la solución que ofreció Alhacén. Tanto los lemas como las soluciones se han modelado en los software de geometría dinámica Cabri II-Plus y Cabri 3-D. El lector interesado en seguir dichas modelaciones debe contar con los programas mencionados para adelantar la lectura de los archivos. En general, estas presentaciones constan de tres partes: (i) formulación del problema (se formula en forma concisa el problema); (ii) esquema general de la construcción (se presentan los pasos esenciales que conducen a la construcción solicitada y las construcciones auxiliares que demanda el problema), esta parte se puede seguir en los archivos de Cabri; y (iii) demostración (se ofrece la justificación detallada de la construcción requerida). Los archivos en Cabri II plus cuentan con botones numerados que pueden activarse haciendo “Click” sobre ellos. La numeración corresponde a la numeración presente en el documento. El lector puede desplazar a su antojo los puntos libres que pueden reconocerse porque ellos se distinguen con la siguiente marca (º). Los puntos restantes no pueden modificarse pues son el resultado de construcciones adelantadas y ajustadas a los protocolos recomendados en el esquema general.

Aportes de la psicología al consumerismo

El presente artículo tuvo como finalidad hallar cuáles han sido los aportes específicos de la Psicología al Consumerismo. Para alcanzar dicho fin se inició con la contextualización del marco teórico relacionado con el consumerismo, partiendo de la historia de la Psicología del Consumidor y sus conceptos más relevantes, continuando con la definición del Consumerismo, las circunstancias específicas de la sociedad actual que han favorecido el afianzamiento en esta temática, así como los aspectos legales generales y los específicos referidos a Colombia. En tercer lugar se realizó una búsqueda rigurosa de material bibliográfico que permitiera ahondar en los aportes de la Psicología, en todas sus ramas, al consumerismo. Finalmente se realizó una reflexión con respecto al papel activo que la psicología debe tomar en el tema del consumerismo, los factores psicológicos que intermedian en este proceso, las consecuencias individuales y sociales, así como el nuevo rol que debe enfrentar el Psicólogo interesado en la Psicología del consumidor.
