Abstract: A computer-implemented method and system automatically adjusts the size of a selection area to aid in a selection of an object generated by a computerized system. The method and system detect a series of movements of a pointer, where the pointer is utilized to select an entity of the object. The series of movements are small and continuous. A set of entities that occupies the selection area is determined and the entities are analyzed for an indication of a level of difficulty in selecting one of the entities. The size of the selection area is reduced when the indication implies that the level of difficulty will be decreased after reducing the size of the selection area.

Abstract: A computer-implemented method of computer vision in a scene that includes one or more transparent objects and/or one or more reflecting objects comprises obtaining a plurality of images of the scene, each image corresponding to a respective acquisition of a physical signal, the plurality of images including at least two images corresponding to different physical signals; and generating a segmented image of the scene based on the plurality of images. This improves the field of computer vision.

Abstract: A computer-implemented method of producing a segmented image of a scene comprises providing a plurality of images of the scene, each image corresponding to a respective acquisition of a physical signal, the plurality of images including at least two images corresponding to different physical signals, and generating the segmented image based on the plurality of images, by determining a distribution of labels that minimizes an energy defined on a Markov Random Field (MRF).

Abstract: A computer-implemented method and system enables visualization of a computer-generated annotation on a real-world object in a real-world environment on a computerized system. The method and system creates a three-dimensional (3D) model of the real-world object, simultaneously displays the 3D model, the real-world object, and the real-world environment on a computer screen, and aligns the displayed 3D model and the displayed real-world object. The visibility of the 3D model is reduced and the 3D model is annotated in a real-world context. Reducing the visibility of the 3D model causes the annotation to appear on the displayed real-world object.

Abstract: A computer-implemented method for manipulating at least one three-dimensionally modeled object (O1) in a three-dimensional scene displayed on a computer display. The method displays, in the three-dimensional scene, a cursor (C) controlled by a pointing device (PD). The cursor has a shape representing three axes (X, Y, Z) of a coordinate system. Next the method selects an object of the three-dimensional scene; and detects a drag operation performed by a user using the pointing device. The drag operation translates the cursor and selects an axis of the coordinate system as a function of the translation of the cursor. Also the method performs a manipulation of the selected object. The manipulation depends on the selected axis and on a length (L) of the translation of the cursor (PP) along the selected axis.

Abstract: Described herein is a computer-implemented method for designing a three-dimensional modeled physical part. The method comprises providing a boundary representation of the modeled physical part, selecting, upon user action, a subset of the boundary representation that represents a geometric feature, identifying all the subsets of the boundary representation that are similar to the selected subset of the boundary representation by applying a feature similarity function.

Abstract: The invention notably relates to a computer-implemented method for compressing a three-dimensional modeled object. The method comprises providing a mesh of a three-dimensional modeled object, parameterizing (u,v) the mesh on a two-dimensional plane, converting the parameterized mesh into an image I, defining a grid of cells from the image I, each cell being defined by a set of control points, computing a relevance of each cell of the grid, determining at least one cell having a relevance lower than a pre-determined threshold, resizing the at least one determined cell and computing a resulting grid, computing a transformation for each pixel of the image from the resulting grid, and applying the computed transformation to the image I.

Abstract: The invention notably relates to a computer-implemented method for simulating a 3D scene. The simulation is carried out with a set of computing resources running in parallel. The method comprises partitioning a 3D scene into a plurality of zones. Each zone is sized to satisfy real-time computing constraint by one computing resource of the set. The method comprises assigning each zone of the plurality to a computing resource, computing an estimation of a load of each computing resource and determining whether one or more computing resources are over-loaded or under-loaded, computing, for each zone, a contribution of the zone to the load of the computing resource to which the zone is assigned, reassigning one or more zones of a computing resource that is over-loaded or under-loaded to another computing resource, the reassignment resulting from the computed contributions of the zones with a combinatorial optimization algorithm.

Abstract: The invention notably relates to a computer-implemented method for learning a function configured for reconstructing, for a class of real objects, a 3D modeled object that represents an instance of the class from a depth map of the instance. The method comprises providing a parametric model of the class, creating a database, and learning the function with the database. The method improves the 3D reconstruction of a real object from a depth map.
