Abstract:
The present invention relates to an apparatus and a method for correcting the deformations that appear, in both bidimensional and stereoscopic vision, when images generated in compliance with the linear perspective rules are viewed from a point of view not corresponding to the center of projection of the perspective. The corrections are determined by a technique that tends to represent the images as if each point that constitutes them were captured with the lens aimed at it. In such hypothesis of lens aiming, the position gradient of the points to be represented is calculated, and the coordinates of the positions that the points must take in the image plane are obtained by integrating the components of such gradient. The application range of the method is very wide, due to the various embodiments and numerous variants it allows.
Abstract:
The present invention relates to a method and a user equipment (105) comprising communication means adapted to attempt to access a mobile telecommunications network (107) and to receive from said network (107) information about the presence of access restrictions to the network (107); said equipment (105) also comprises an access management module (106) configured for determining, in the presence of access restrictions to the network (107), a wait time (Tbarring) that must elapse, at the least, between successive verifications of the possibility of accessing said network (107), wherein said wait time (Tbarring) is determined at least on the basis of the result of at least one previous attempt to access the network (107) by said user equipment (105).
Abstract:
