  • Patent number: 11262837
    Abstract: A system and method is provided for improving sensor precision. In a training phase, a relatively low precision sensor system and a relatively high precision sensor system may record relatively low precision and relatively high precision training motion signals respectively of substantially the same training scene. Machine learning may be performed to generate a transformation mapping information from the relatively low precision training motion signal to the relatively high precision training motion signal. In a run-time phase, a run-time sensor system having a precision significantly less than the precision of the relatively high precision sensor system, may record run-time motion signals of a run-time scene. The run-time motion signal may be transformed using the transformation to generate a transformed run-time motion signal with a precision significantly greater than the precision of the run-time sensor system.

  • Patent number: 11100314
    Abstract: A device, system and method is provided for estimating movement based on a human movement model in a virtual, augmented or mixed reality environment. In an offline phase, a human movement model may be stored that assigns a non-uniform probability of spatiotemporal representations of movements that occur in a human body. In an online phase, a user's movements may be recorded. The user's movements may be estimated by spatiotemporal representations of a plurality of (N) degrees of freedom (DOF) that maximize a joint probability comprising a first probability that the measured movements match the estimated movements and a second probability that the human movement model assigns to the spatiotemporal representations of the estimated movements. A virtual, augmented or mixed reality image may be displayed that is rendered based on the NDOF spatiotemporal representations of the estimated movements.

In an offline phase, a human movement model may be stored that assigns a non-uniform probability of spatiotemporal representations of movements that occur in a human body. In an on-line phase, a user's movements may be recorded. The user's movements may be estimated by spatiotemporal representations of a plurality of (N) degrees of freedom (DOF) that maximize a joint probability comprising a first probability that the measured movements match the estimated movements and a second probability that the human movement model assigns to the spatiotemporal representations of the estimated movements.

  • Patent number: 7180536
    Abstract: The invention provides a method for producing a series of stereoscopic pairs of images that can be displayed one after the other as a stereoscopic movie. The sequence of stereoscopic pairs is derived from a sequence of consecutive images of a scene that is obtained by standard techniques using standard equipment. A first image of a pair of images comprising the right and left images of each frame of the stereoscopic series of images is selected from the original sequence of images. Its stereo partner is either selected from the original sequence and/or is generated by transforming images selected from the original sequence of images.
