According to an aspect, a real-time active stereo system includes a capture system configured to capture stereo image data, where the image data includes a plurality of pairs of a reference image and a secondary image, and each pair of the plurality of pairs relates a different temporal window. The real-time active stereo system includes a depth sensing computing system including at least one processor and a non-transitory computer-readable medium having executable instructions that when executed by the at least one processor are configured to execute a local stereo reconstruction algorithm configured to compute spacetime descriptors from the plurality of pairs of the stereo image data and generate depth maps based on the spacetime descriptors.

Techniques of rendering images includes generating signed distance values (SDVs) along a ray from a specified viewpoint in terms of projected distances along that ray from given depth images. For each pixel in an image of from the perspective of the specified viewpoint, a ray is traced into the three-dimensional scene represented by the image. An iterative step is performed along the ray, obtaining in each iteration a three-dimensional world-space point p. The result is the signed distance sas measured from depth view D. If the absolute value of the signed distance sis greater than some truncation threshold parameter, the signed distance sis replaced by a special undefined value. The defined signed-distance values are aggregated to obtain an overall signed distance s. Finally, the roots or zero set (isosurface) of the signed distance field is determined.

A job that receives as input a data stream is executed. For the job, it is iteratively determined a backlog growth over a first period of time; a backlog volume; and whether to adjust a quantity of processing resources. For each iteration for which the quantity of processing resources allocated to the job are determined to be adjusted, adjusting the quantity of processing resources allocated to the job. For each iteration for which the quantity of processing resources allocated to the job are determined not to be adjusted, maintaining the quantity of processing resources allocated to the job.
