Patent number: 11017256Abstract: Systems and methods for the rapid analysis of images that are particularly useful in avionic contexts are provided. One specific method describes steps of computing algorithmic complexity and/or logical depth, so as to rapidly categorize objects, comprising images and/or points of interest determined in these images, according to discrete levels of structuring, organization or order. Complex image processing operations may then concern restricted subsections of the images. The complexity or logical depth computing operations may for example comprise steps of losslessly compressing the objects row by row and/or column by column, of determining statistical distributions of the compression rates of these objects, of determining one or more scores on the basis of the compression rates or of statistical moments and of locally or globally categorizing one or more received images. Developments describe system and software aspects.Type: GrantFiled: October 14, 2019Date of Patent: May 25, 2021Assignee: THALESInventors: Christian Nouvel, Sébastien Ellero

Publication number: 20160131914Abstract: Visual display systems are described having means for generating stereoscopic images, a device for visual display of said stereoscopic images having a projector and a semitransparent screen; and a pair of stereoscopic spectacles. The projector according to the invention has an imager and an interference filter, the spectral transmission of which has at least one transmission band of determined width centred around a wavelength, said wavelength being dependent on the incidence of the light on said interference filter. The projector has means allowing the angular position of the filter to be varied between two determined positions so as to transmit, according to the position, either a first spectral band or a second spectral band. The pair of stereoscopic spectacles has a first lens transmitting the first spectral band and blocking the second spectral band and a second lens providing the opposite function.Type: ApplicationFiled: November 5, 2015Publication date: May 12, 2016Inventors: Johanna LUX, Sebastien ELLERO, Philippe AUGEREAU

Publication number: 20120162775Abstract: The general field of the invention relates to binocular helmet viewing devices worn by aircraft pilots. In night use, one of the drawbacks of this type of device is that the significant distance separating the two sensors introduces hyperstereoscopy on the images restored to the pilot. The method according to the invention is a scheme for removing this hyperstereoscopy in the images presented to the pilot by graphical processing of the binocular images. Comparison of the two images makes it possible to determine the various elements present in the image, to deduce therefrom their distances from the aircraft and then to displace them in the image so as to restore images without hyperstereoscopic effects.Type: ApplicationFiled: December 20, 2011Publication date: June 28, 2012Applicant: THALESInventors: Jean-Michel FRANCOIS, Sébastien ELLERO, Matthieu GROSSETETE, Joël BAUDOU
