Abstract: It is provided a computer-implemented method for performing body posture tracking, comprising the steps of collecting (S10) depth measurements of a body with at least one depth sensor; collecting (S20) inertial measurements with at least one inertial sensor attached to the body; and determining (S30) at least one posture of the body as a function of the depth measurements and the inertial measurements. Such a method improves the field of body posture tracking.

Abstract: The invention notably relates to a computer-implemented method for completing an image having at least one hole, the method comprising providing a dictionary of atoms representative of the known part of the image; determining an optimal distribution of atom linear combinations with a process comprising at least one minimization of a respective energy defined on a respective Markov Random Field having nodes and labels, each node corresponding to a respective location of the hole and being associated to a respective label; and filling the hole with the optimal distribution. The invention improves the field of image completion.

Abstract: The invention notably relates to computer-implemented method for resizing an image I. The method comprises the steps of: providing the image I to resize; and providing an image significance by computing a significance of each pixel in the image to resize. An original spatial domain (?) of the significance image is extracted. A transformation T?, parameterized as an interpolating spline by a set of control points, is provided from ? to a resized spatial domain ??; subdividing ? into cells, each cell being defined by a subset of control points of the set. For each cell, a weighted average of the significance of the pixels in the cell is computed, the weighted average being computed using the interpolating spline. The cells of ? are deformed by displacing one or more control points of the cells having a lesser weighted average. The transformation T? over a spatial domain of the image I is computed using the displaced one or more control points.
