Low-resolution tile processing for real-time bokeh
摘要:
Methods and apparatuses are disclosed for generating real-time bokeh in images. An example method may include receiving an image, partitioning the image into a plurality of tiles, and designating each of the plurality of tiles as one of a fully foreground tile, a fully background tile, and a mixed tile. Either the fully background tiles or the fully foreground tiles may be processed using a tile-based filtering operation to generate a number of replacement tiles, and the mixed tiles may be processed to generate a number of replacement mixed tiles. An output image nay be generated based on the replacement tiles, the replacement mixed tiles, and either unaltered fully foreground tiles or unaltered fully background tiles.
