    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: The invention provides a video codec. In one embodiment, the video codec is coupled to an outer memory storing a reference frame, and comprises an interface circuit, an in-chip memory, a motion estimation circuit, and a controller. The interface circuit obtains in-chip data from the reference frame stored in the outer memory. The in-chip memory stores the in-chip data. The motion estimation circuit retrieves search window data from the in-chip data with a search window, and performs a motion estimation process on a current macroblock according to the search-window data. The controller shifts the location of the search window when the current macroblock is shifted, marks a macroblock shifted out from the search window as an empty macroblock, and controls the interface circuit to obtain an updated macroblock for replacing the empty macroblock in the in-chip memory from the reference frame stored in the outer memory.

    Abstract: An embodiment of a computer-implemented method generates a filtered set of region proposals for a digital image processing network. The method comprises generating a keypoint count map for a digital image, wherein the keypoint count map indicates how many keypoints have been detected near different pixels in the digital image. The method also comprises generating a keypoint integral image, wherein the keypoint integral image comprises a summed area table that is based on the keypoint count map. The method also comprises generating object existence indicators for an initial region set for the digital image based on the keypoint integral image, and extracting a keypoint-filtered region set from the initial region set based on the object existence indicators. The method may also comprise using the keypoint-filtered region set as region proposal input for an object proposal subsystem. Other embodiments are described and claimed.
