1. A method, comprising: converting pixel information of a background image from an non-luminance-isolating color space to a luminance isolating color space according to a mask of a foreground image, wherein the pixel information comprises color information for a plurality of pixels indicated by the mask of the foreground image; modifying luminance values for the plurality of pixels of the converted pixel information to increase the contrast between the plurality of pixels of the converted pixel information and surrounding pixels of the background image; blurring at least a part of the plurality of pixels of the converted pixel information, wherein said blurring comprises adjusting each of one or more of the plurality of pixels according to one or more pixels adjacent to each respective one or more of the plurality of pixels; converting the pixel information from the luminance isolating color space back into the non-luminance-isolating color space; and blending the foreground image with the background image.
