Abstract
A graphic and video are blended by controlling the relative transparency of corresponding pixels in the graphic and the video through the use of blending coefficients. One example of a blending coefficient is an alpha signal used in conjunction with a keyer. The value of a blending coefficient for a pixel in the graphic is based on the luminance and chrominance characteristics of a neighborhood of pixels in the video. Inclusions and exclusions are set up which define how the neighborhood of pixels is used to create or change a particular blending characteristic.
Claims50
A method for blending images, comprising the steps of:
- selecting a first portion of a first image, said first portion of said first image includes different color values;
- storing information about said different color values;
- receiving a first video image after said step of selecting;
- accessing color data for said first video image;
- comparing said color data to said stored information about said different color values;
- and
- blending a second image with said first video image at least partially based on said step of comparing.
One or more processor readable storage devices having processor readable code embodied on said one or more processor readable storage devices, said processor readable code for programming one or more processors to perform a method comprising the steps of:
- receiving a selection of a first portion of a first image, said first portion of said first image includes different color values;
- storing information about said different color values;
- receiving a first video image after said step of selecting, said first video image includes color data;
- comparing said color data to said stored information about said different color values;
- and
- blending a second image with said first video image at least partially based on said step of comparing.
An apparatus, comprising:
- one or more processors;
- an input device in communication with said one or more processors;
- an output device in communication with said one or more processors;
- a storage device in communication with said one or more processors, said processor programmed to preform a method comprising the steps of:
- receiving a selection of a first portion of a first image, said first portion of said first image includes different color values,
- storing information about said different color values,
- receiving a first video image after said step of selecting, said first video image includes color data,
- comparing said color data to said stored information about said different color values, and
- blending a second image with said first video image at least partially based on said step of comparing.
A method for blending images, comprising the steps of:
- receiving video of an environment;
- selecting a first region in said video, said first region includes a first set of different color values;
- creating inclusion criteria describing said first set of different color values;
- selecting a second region in said video, said second region includes a second set of one or more color values;
- creating exclusion criteria describing said second set of one or more color values, said first set of color values overlap with said second set of color values;
- identifying a target area in said video after said steps of creating inclusion criteria and creating exclusion criteria;
- comparing said color data for said target area to said inclusion criteria and said exclusion criteria;
- and
- blending a graphic with said target area at least partially based on said inclusion criteria and said exclusion criteria.
