摘要： A system and method for stereo matching of at least two images, e.g., a stereoscopic image pair, employing a global optimization function, e.g., a belief propagation function, that utilizes dynamic programming as a preprocessing step are provided. The system and method of the present disclosure provide for acquiring a first image and a second image from a scene, estimating the disparity of at least one point in the first image with at least one corresponding point in the second image, and minimizing the estimated disparity using a belief propagation function, e.g., a global optimization function, wherein the belief propagation function is initialized with a result of a deterministic matching function, e.g., dynamic programming, applied to the first and second image to speed up the belief propagation function. The system and method further generates a disparity map from the estimated disparity and converts the disparity map into a depth map.

摘要： A method, apparatus and system for synchronizing between two recording modes includes identifying a common event in the two recording modes. The event in time is recognized for a higher accuracy mode of the two modes. The event is predicted in a lower accuracy mode of the two modes by determining a time when the event occurred between frames in the lower accuracy mode. The event in the higher accuracy mode is synchronized to the lower accuracy mode to provide sub-frame accuracy alignment between the two modes. In one embodiment of the invention, the common event includes the closing of a clap slate, and the two modes include audio and video recording modes.

摘要： A method and system for modeling light in time and space are provided. The method and system of the present disclosure collect light readings, e.g., on a motion picture set, at different positions and times to build a light model to be used for visual effects (VFX) compositing. The light model represents the light distribution across space and/or time for a predetermined physical space. Using the light model, the lighting can then be predicted or interpolated at intermediate or other positions and/or times for which no specific light readings were obtained. The light models can be used for rendering objects (e.g., natural or CG elements) in a scene as if they were in that space.
