摘要： An active set of discrete texture traces to a target point is determined in a first video frame and is applied to a second video frame to detect the target location in a second video frame. An estimate is made of the target location in the second video frame. A score map is computed of an area of locations. A location with a highest score in the score map is the new target location. If a threshold value is not met the active set of texture traces is stored. A score map for each of stored active sets is computed to determine the target location. If no score meets the threshold the target location in a previous video frame is made the current target location and a new active set of discrete texture traces is determined. Systems that implement the steps of the methods are also provided.

摘要： Object detection includes providing an image and determining at least one feature point. The at least one feature point defines a location of an image patch used for determining a feature descriptor, and the image patch defines an image area of the image. The feature descriptor is generated based on respective image intensities of a number of respective pairs of pixels with two dimensional coordinates located inside the image patch. An n-th component of the feature descriptor for an n-th pair of pixels is derived. A threshold is set depending on the number. The feature descriptor is generated by an arrangement of the M components. An indication signal is generated for a detected object when the feature descriptor is within a predefined distance to a reference feature descriptor.

摘要： Computer assisted design data is rendered in the cloud. A client-server relationship is provided for 3D rendering. To reduce the burden on the server, the 3D rendering adapts based on the client capabilities. Where possible, some of the 3D rendering is performed by the server and some by the client machine. The 3D rendering by the client machine may be limited to avoid transfer of geometrical data of the CAD data. Different textures or shaders are used for rendering images associated with motion. Dictionary information is accumulated by the client machine to reduce the number of coefficients later transferred to the client machine for 3D rendering. The model represented by the CAD data is used to predict rendered images so that video compression may be performed. The server sparsely renders an image and compressive sensing is used by the client machine to generate the complete image.

摘要： A system and methods for geometric calibration and use of head-worn multi-camera eye tracking system are provided. The system calibrates the internal and external parameters of the cameras as well as the parameters of a compact geometric model of the human eye. An exo-camera determines a relative pose with regard to a computer monitor and endo-cameras determine the eyeball position and orientation. An endo-exo calibration and an endo-eye calibration each with an optimization step are included. A homography and a joint optimization step are also provided. A single point calibration re-establishes calibration. The system in operational mode determines a user's gaze direction to perform a computer input function.

摘要： A system and methods for activating and interacting by a user with at least a 3D object displayed on a 3D computer display by at least the user's gestures which may be combined with a user's gaze at the 3D computer display. In a first instance the 3D object is a 3D CAD object. In a second instance the 3D object is a radial menu. A user's gaze is captured by ahead frame containing at least an endo camera and an exo camera worn by a user. A user's gesture is captured by a camera and is recognized from a plurality of gestures. User's gestures are captured by a sensor and are calibrated to the 3D computer display.
