Abstract: The process of the invention enables the spatial color alterations of a silver image to be taken into account according to one of its main axes (19). The process of the invention enables the altered or faded colors of the silver image to be restored automatically, without depending on the skills of an operator to perform a color restoration treatment. A digital image (12) is divided into adjacent pixel strips (18), arranged perpendicular to the direction (19) according to which the color alteration occurs. For each of these strips (18), optical density distributions of each pixel are calculated and compared with reference optical density values. The process of the invention enables the automatic correction of all the strips (18) comprising the altered pixels, by applying a linear transformation enabling the transformation of the optical density values of the altered pixels, into the optical density values of a pixel strip of least degradation.

Abstract: The invention is to provide a recording process that enables the density of recorded information to be increased on a two-dimensional medium comprising a printing surface, for example a strip of light sensitive film. The process is for a recording system for digital data (1) and a recording medium (7) to record the encoded data, for example a strip of photographic film. The process is used in particular to code data to be recorded at high density, for example the digital data of still or moving images, text, or sound.

Abstract: A system and method for to establish a wireless group call from one of a plurality of communication units to others communication units includes a first step of receiving, from a requesting communication unit a request for a group call with other communication units of the group. A next step includes allocating a common downlink channel for the group call. A next step includes allocating a dedicated uplink channel for the requesting communication unit. A next step includes switching one of the communication units between the common channel mode and a dedicated channel mode depending upon performance criteria.

Abstract: The present invention is in the field of imaging and more specifically image analysis. An object of the invention is to provide for a method which restores a digitized image or a series of digitized images automatically, by eliminating straight or virtually straight scratches in the images. The method of the invention eliminates scratches in still or animated digital images by using the residual image information in the altered areas of the images. This method can be used in the field of the restoration of films and television documents and for retouching and restoring photographic images.

Abstract: The present invention is in the technological field of imaging and more specifically image analysis. The present invention relates more particularly to an interactive process that lets a user select and validate partially or fully the result supplied by an automatic detection process of digital image data. The invention process enables a display on the display screen of a terminal, one digitized original image, accompanied by a digital image of the graphic representation of candidate zones representative of candidate elements to be extracted from the original image. The user can select and validate the candidate zones or parts of candidate zones that he/she wishes to validate or invalidate. The invention process is used advantageously to renovate images recorded on silver or magnetic supports. The conventional silver supports of these images are generally constituted of photographic film or paper.
