APPARATUS AND METHOD FOR AUGMENTING A VIDEO IMAGE

摘要

A method of augmenting a video image comprises the steps of estimating the extent of an identified surface captured within the video image and identifying skin pixels within a test area corresponding to the estimated extent of the identified surface within the video image. The method also includes extrapolating positions for skin pixels within the video image that are outside the estimated extent of the identified surface based upon the identified skin pixels, generating a mask from a combination of identified skin pixels and extrapolated skin pixels, and setting an extent of a computer graphic to be superposed substantially on top of the identified surface within the video image. The extent is greater than the estimated extent of the identified surface. The method further includes superposing the graphical augmentation of the video image responsive to the generated mask.
