Abstract: Aspects of the present disclosure relate to systems and methods for selectively processing tiles of a captured image. The captured image may be parsed into a plurality of tiles. A subset of the plurality of tiles may be selected based at least in part on at least one metric. The selected tiles may be processed according to a first technique, while each unselected tile may be selectively processed according to one or more techniques different from the first technique. The first technique and the one or more techniques may each be either an image demosaicing technique or an image denoising technique.

Abstract: Methods and apparatuses for image processing are disclosed. An example method may include receiving an image to be processed. The method may further include selecting a pixel of the image. The method may also include determining, for each of a plurality of directions through the selected pixel, a gradient in intensity based on the selected pixel and a set of one or more neighboring pixels along the corresponding direction. The method may further include determining, for each of the plurality of directions, if the set of one or more neighboring pixels is selected for adjusting the intensity of the selected pixel based on the corresponding determined gradient in intensity. The method may also include determining a noise reduction filter for the selected pixel based on the selected sets of one or more neighboring pixels. The method may further include applying the determined noise reduction filter to the selected pixel of the image.

Abstract: A system and method are disclosed for generating an overshoot-corrected set of edges of an input image. An example method includes, receiving an input image, and generating a coarse set of edge pixels based on the received input image For each given pixel in the coarse set of edge pixels, the example method includes identifying a first pixel of the input image that corresponds to the given pixel in the coarse set of edge pixels; and determining a modified edge pixel for the given pixel based at least in part on differences between the first pixel and one or more pixels of the input image that are located within a vicinity of the first pixel. The example method further includes generating an edge-enhanced version of the input image based at least in part on the modified edge pixels.
