20090313792 | Clamping collar having a die-stamped fastening stud - The collar is made from a metal strip formed into a loop, and has a fastening stud and an ear that project radially. The ear is provided with an aperture into which a free end portion of the stud can be inserted for the purposes of fastening and of tightening the collar. The collar further has engagement surfaces for engaging with a tightening tool, which surfaces project radially and are situated respectively behind the ear and behind the stud. The stud and the engagement surface that is situated behind the stud are formed in a common projection and have side cheeks that are raised relative to the plane of the strip, and that are common to them. The ear is also formed by a projection. | 12-24-2009 |

20130142397 | Global and Dense Motion Estimation - The invention relates to a method which uses a series of images sensed by an image sensor including at least one preceding image and one following image to estimate movement. A first estimated movement is initially obtained by estimating the total movement from the preceding image to the following image. Next, an image compensated according to the first estimated movement is obtained from either one of the preceding and following images. Then, a second estimated movement is obtained by estimating dense movement between the compensated image and the other from the preceding and following images. Next, a residual value of global movement is determined. Finally, if the residual value is lower than a threshold value the second estimated movement is provided; otherwise, the preceding steps are repeated. The first estimated movement is determined by applying a binary image mask, and if during step /e/ the steps /a/ to /e/ are repeated, said steps are performed by applying a binary image mask updated according to the second estimated movement. | 06-06-2013 |

20150358637 | ESTIMATION OF THE MOVEMENT OF AN IMAGE - A method for estimation of motion in a series of images captured by an image sensor comprising an estimation of motion vectors at a plurality of points from an image by an operation, done at each of the points from the plurality of points, of minimization of a functional of motion vectors comprising the sum of a data term and a regulation term, where the data term is made up of the product of a weighting term which is a function of the degree of regularity of the estimated motion vectors and a data linkage term which is a function of the spatial-temporal gradients of the brightness near points located in a neighborhood of a point, where the regulation term supplies a result to the minimization operation for the points near which the minimization of the data term does not allow estimating a unique solution. | 12-10-2015 |
