Image editing using level set trees

摘要

A method comprising: mapping an image onto multiple level sets connected by multiple branches, wherein each of said level sets corresponds to a predefined range of values for an attribute of said image; associating multiple pixels of said image to said multiple level sets in accordance with the value of each pixel; identifying a source level set associated with a source pixel of said multiple pixels; for each of said multiple pixels, determining that a distance between said source pixel and one of said multiple pixels is within a predefined threshold, wherein said distance is calculated as a function of a first distance between said source level set and said level set associated with said one of said multiple pixels; in one embodiment, the determined distance is applied to an image processing application to produce a processed image, and the processed image is rendered on a rendering medium.

1. A method for segmenting an image, the method comprising using at least one hardware processor for:
mapping an image onto a level set tree, wherein said level set tree comprises multiple level sets connected by multiple branches, and wherein each of said multiple level sets corresponds to a predefined range of values for an attribute of said image; associating multiple pixels of said image to said multiple level sets of said level set tree, in accordance with a value for each of said pixels for said attribute; identifying a first source level set of said multiple level sets associated with a first source pixel of said multiple pixels; determining that an image-domain distance between said first source pixel and one of said multiple pixels is within a predefined threshold, wherein said image-domain distance is calculated as a function of a first level-set tree distance between said first source level set and said level set associated with said one of said multiple pixels; associating said one of said multiple pixels with a first pixel set corresponding to said first source pixel; and rendering said first pixel set on a rendering medium.
