摘要： This application provides a three-dimensional (3D) expression base generation method performed by a computer device. The method includes: obtaining image pairs of a target object in n types of head postures, each image pair including a color feature image and a depth image in a head posture; constructing a 3D human face model of the target object according to then image pairs; and generating a set of expression bases of the target object according to the 3D human face model of the target object. According to this application, based on a reconstructed 3D human face model, a set of expression bases of a target object is further generated, so that more diversified product functions may be expanded based on the set of expression bases.

摘要： A depth camera assembly (DCA) determines depth information. The DCA projects a dynamic structured light pattern into a local area and captures images including a portion of the dynamic structured light pattern. The DCA determines regions of interest in which it may be beneficial to increase or decrease an amount of texture added to the region of interest using the dynamic structured light pattern. For example, the DCA may identify the regions of interest based on contrast values calculated using a contrast algorithm, or based on the parameters received from a mapping server including a virtual model of the local area. The DCA may selectively increase or decrease an amount of texture added by the dynamic structured light pattern in portions of the local area. By selectively controlling portions of the dynamic structured light pattern, the DCA may decrease power consumption and/or increase the accuracy of depth sensing measurements.

摘要： Disclosed are methods, apparatus and systems for real-time gesture recognition. One exemplary method for the real-time identification of a gesture communicated by a subject includes receiving, by a first thread of the one or more multi-threaded processors, a first set of image frames associated with the gesture, the first set of image frames captured during a first time interval, performing, by the first thread, pose estimation on each frame of the first set of image frames including eliminating background information from each frame to obtain one or more areas of interest, storing information representative of the one or more areas of interest in a shared memory accessible to the one or more multi-threaded processors, and performing, by a second thread of the one or more multi-threaded processors, a gesture recognition operation on a second set of image frames associated with the gesture.

摘要： The present invention discloses a noise processing method and apparatus. The method includes: selecting a pixel in an area array, which is formed by arranging a plurality of pixels in a matrix; obtaining pre-stored depth information corresponding to the pixel; performing pixel dispersion calculation according to the depth information corresponding to the pixel, to obtain at least one dispersion of the pixel, the dispersion being used to indicate a degree of dispersion between the pixel and another pixel in the area array; and identifying the pixel as a noise and removing the pixel from the area array when the at least one dispersion of the pixel is greater than a preset threshold. According to the above method, the dispersion between the pixel and the another pixel in the area array is calculated according to the depth information corresponding to the pixel, and the pixel is identified as a noise and is removed from the area array when the at least one dispersion of the pixel is greater than the preset threshold. Therefore, noises in the area array may be identified and removed, which resolves a technical problem that generated noises may affect accuracy of the depth information.
