Abstract: Skin smoothing is applied to images using a bilateral filter and aided by a skin map. In one example a method includes receiving an image having pixels at an original resolution. The image is buffered. The image is downscaled from the original resolution to a lower resolution. A bilateral filter is applied to pixels of the downscaled image. The filtered pixels of the downscaled image are blended with pixels of the image having the original resolution, and the blended image is produced.

Abstract: In an embodiment, at least one computer readable storage medium has instructions stored thereon for causing a system to send, from a processor to a task execution device, a first call to execute a first subroutine of a set of chained subroutines. The first subroutine may have a first subroutine output argument that includes a first token to indicate that first output data from execution of the first subroutine is intermediate data of the set of chained subroutines. The instructions are also for causing the system, responsive to inclusion of the first token in the first subroutine output argument, to enable the processor to execute one or more operations while the task execution device executes the first subroutine. Other embodiments are described and claimed.
