Embodiment Construction
[0024] The following description outlines methods for improving digital image processing. More specifically, methods for improved edging are disclosed that can be applied to extracted foreground parts of a scene without additional user interaction. Furthermore, it can be seen that the methods disclosed herein can be applied to any desired portion of an image (eg, object, foreground, etc.).
[0025] As can be seen, the edge trimming methods described herein limit artifacts (eg, see artifacts in FIGS. 2A-B ) and / or support restoration of foreground color, eg, limit color bleeding from the background. In one implementation, trimming can be applied while estimating an alpha mask around object boundaries and the color of foreground pixels to limit the negative impact of blurring and / or blending pixels along smooth object boundaries.
