  • Patent number: 10861166
    Abstract: A method for restoring images in a sequence of images, including, when it is applied to a first image in the image sequence: estimating an item of information representing a global motion of a background of the first image with respect to a second image; compensating for said global motion of the background in the second image in order to obtain an adjusted version of the second image, referred to as the adjusted second image; obtaining a contour of an object of the first image by applying a segmentation method using the adjusted second image; using the contour of the object thus obtained in order to estimate an item of information representing a global motion of the object; and applying to the first image an image restoration method using the information representing the estimated global motion of the background and the estimated global motion of the object.

  • Patent number: 10837777
    Abstract: The invention relates to a device for maintaining the attitude of a carrier, the device comprising three primary gyroscopes (1, 2, 3) that are arranged to measure primary speeds of rotation (Rbc) of a carrier about three primary axes, a secondary gyroscope (4) that is arranged to measure a secondary speed of rotation (Rhp) of the carrier about a secondary axis that is different from each of the primary axes, a video camera (5) having an optical axis that is different from each of the primary axes, and a data processing module (6) that is configured to estimate scale-factor and drill errors that corrupt the primary speeds of rotation (Rbc) using data issued from the secondary speed of rotation (Rhp) and images acquired by the video camera (5), and to correct the primary speeds of rotation with said estimated errors.
