  • Matting method for extracting foreground object and apparatus for performing the matting method
    Patent number: 9489588
    Abstract: A matting method and apparatus for extracting a foreground object are disclosed. The matting method includes extracting one or more pixels from an input image and a trimap; calculating a first processing cost by extracting one or more nonlocal neighboring pixels; calculating a second processing cost by extracting one or more local neighboring pixels; and performing matting on the input image by estimating an opacity value for each of the extracted pixels based on the first and second processing costs. Accordingly, it is possible to perform high-quality image matting, and thus increase a performance in extracting a to foreground object from the input image, so that the matting method and apparatus can be applied to multiple-purpose image editing software.
