Patent number: 10614559Abstract: A decamouflaging method includes: obtaining image representing a scene including a multispectral image including components in the spectral domain ranging from the visible domain to the short-wavelength infrared and a thermal image including a component in the medium infrared and/or the long-wavelength infrared; extracting a sub-part (“window”) from each of the images obtained at a given position; applying a contrast accentuation procedure to the window extracted from the multispectral image allowing an improved window to be obtained where contrast between pixels corresponding to the object and pixels not corresponding to the object is accentuated; forming a multicomponent window, the improved window obtained and the window extracted from the thermal image each supplying a component of the multicomponent window; and applying the procedure to the multicomponent window; generating an image by inserting the improved window obtained by applying the procedure to the multicomponent window in a receiving image repreType: GrantFiled: November 10, 2016Date of Patent: April 7, 2020Assignee: SAFRAN ELECTRONICS & DEFENSEInventors: Nicolas Roux, Philippe Foubert, Thierry Touati, Marc Bousquet

Patent number: 10600200Abstract: Method for viewing a laser spot included in a multispectral image representing an optical field composed of pixels including a plurality of components, the laser spot being produced by a laser pointer and having a wavelength taking values in a range of wavelengths dependent on operating temperatures of the laser pointer. The method includes: obtaining a multispectral image in which each component corresponds to the same instant of acquisition and represents a spectral band in a plurality of spectral bands covering continuously a spectral domain comprising said range of wavelengths; applying a contrast-accentuation procedure to a subpart of the multispectral image comprising the laser spot in order to obtain a subpart in which a contrast between the laser spot and a background is improved; and generating an image allowing display of the laser spot using information obtained following the application of said procedure.Type: GrantFiled: July 11, 2016Date of Patent: March 24, 2020Assignee: SAFRAN ELECTRONICS & DEFENSEInventors: Nicolas Roux, Philippe Foubert, Philippe Patry, Pierrick Guiset, Thierry Touati

Patent number: 10089536Abstract: The invention relates to a method for analyzing a multispectral image (10), which includes designing a detection image from the values of a revealing function that quantifies a content shift in the multispectral image between two areas. The revealing function is applied between a target area and a background area, inside a window which is determined around each pixel. The revealing function values are determined from integral images of order one, and optionally also of order two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.Type: GrantFiled: November 26, 2014Date of Patent: October 2, 2018Assignee: Sagem Défense SécuritéInventors: Marc Bousquet, Maxime Thiebaut, Nicolas Roux, Philippe Foubert, Thierry Touati

Patent number: 9922407Abstract: The invention relates to a method for analyzing a multispectral image (10), which includes designing a detection image from signal-to-noise ratio values. The signal-to-noise ratio values relate to the content of the multispectral image inside a window which is determined around each pixel, when the contrast in the window is maximized by a Fischer projection. The signal-to-noise ratio values at calculated from integral images of order one and two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.Type: GrantFiled: November 26, 2014Date of Patent: March 20, 2018Assignee: Sagem Defense SecuriteInventors: Marc Bousquet, Maxime Thiebaut, Nicolas Roux, Philippe Foubert, Thierry Touati

Patent number: 9524564Abstract: The inventive method for viewing of a multi-spectral image by an operator uses contrast optimization by Fisher projection. The Fisher projection is determined and applied within a window (F1, F2, F3, . . . ) that is smaller than a display screen matrix (1) used by the operator. The window is moved for successive updates of a depiction of the image that is displayed, while creating a remanence of the positions of the earlier windows and elements that were exposed in some of said earlier windows. The implementation of the method is particularly simple and intuitive for the operator, so as to improve the reliability and effectiveness of his or her monitoring.Type: GrantFiled: September 25, 2014Date of Patent: December 20, 2016Assignee: Sagem Defense SecuriteInventors: Eric Agostini, Maxime Thiebaut, Nicolas Roux, Philippe Foubert, Thierry Touati
