User interface for selecting paths in an image

摘要

A method, performed by a computer, of facilitating selection by a user of one path from a set of directed paths in an image, partly overlapping but not constituting a directed tree structure, each path beginning at a root and ending at an end point, the method comprising:
a) receiving from the user an indication of a specified location in the image;b) identifying a specified path part that best matches the indication of the specified location; andc) suggesting primarily a single path chosen from among two or more paths in the set which include the specified path part, but do not all follow a same route before the specified path part, and at least one of which separates from another path somewhere along its length.

1. A method, performed by a computer, of facilitating selection by a user of one path from a set of directed paths in an image, comprising:
a) generating the set of directed paths from a data representation comprising path segments in the image connected at their ends to other path segments, with each directed path in the set being an ordered sequence of connected path segments in the data representation, the different paths partly overlapping but the data representation not constituting a directed tree structure, each path beginning at a root and ending at an end point; b) receiving from the user an indication of a specified location in the image; c) identifying a specified path segment that best matches the indication of the specified location; and d) choosing a single path from among two or more paths belonging the set of directed paths, which two or more paths all include the specified path segment, but do not all follow a same route before the specified path segment, and at least one of which separates from another path somewhere along its length, and pointing out the chosen single path as a primary suggestion to the user.
