Abstract

The invention discloses a full-automatic fine image matting device and method. The full-automatic fine image matting device comprises an SLR camera, the SLR camera is connected with a data interface, the data interface is respectively connected with an environment shooting unit and a control center, the control center comprises a background recognition module, a rapid image matting module, an automatic calculation module, a cluster-based sampling point optimization selection module, a fine image matting module and an image memorizer. The invention further relates to a method fine conducting fine image matting with the full-automatic fine image matting device. Manual labeling is not needed in the whole image matting process, full-automatic image matting in non-transparent and semi-transparent areas is completely achieved, and the image matting quality and the image matting efficiency are improved.

Description

Technical field [0001] The invention relates to a fully automatic fine keying device and a fine keying method. Background technique [0002] Keying technology is widely used in film post-processing, two-dimensional graphic art, television, advertising, video post-production and other fields. Most typically, in the process of film production, the director uses keying and synthesis techniques to synthesize images shot at different times and locations into the same scene to achieve special artistic effects. At present, the keying technology of static images in film and television post-processing usually uses a monochrome background. The background must be a certain fixed known color, such as blue or green. The sample is taken in a relatively uniform lighting environment in the studio, and then passed The keying algorithm obtains the foreground and its corresponding Alpha channel. [0003] The keying technology with Alpha channel calculation needs to treat the pixels in the digital i...
