Abstract
Foreground images, such as cursors, may be displayed over an image by selecting individual pixel colors to contrast with surrounding background pixels. The background pixels in, around and behind the foreground image may be converted from a red-green-blue (RGB) color space to a luminance isolating color space, such as YUV, HSL or the like. The converted pixel information may be copied, stored, or drawn into a separate compositing window. After converting to the luminance isolating color space, the luminance values of the pixels may be adjusted to increase the contrast between the foreground image and the background image. Portions of the foreground image may also be blurred, such as by applying a Gaussian or box blur, such as to soften the edges. The pixel information may then be converted back into the RGB color space and blended with the background information using alpha information for the foreground and background images.
