Patent Images
1. A computer-implemented method for assigning attributes to an image, the method comprising:
- displaying an unsegmented image;
marking by a user a plurality of pixels in a region of the unsegmented image as a single marked area by a single scribble covering the plurality of pixels, the single marked area defines, for a current iteration, at least one target attribute for the region;
determining according to the target attribute an optimal function that defines at least one respective attribute of pixels in the region;
assigning the at least one respective attributes to pixels in the region according to the optimal function; and
segmenting the unsegmented image in accordance with the at least one respective attribute.

Abstract
A computer-implemented method for assigning attributes to an image. The method comprises allowing a user to mark a plurality of pixels of an image as a single marked area by a single scribble, the single marked area defines, for a current iteration, a target attribute, determining according to the target attribute an optimal function that defines at least one respective attribute of pixels in the image, assigning the at least one respective attribute to pixels in the image according to the optimal function, and displaying the at least one attribute of the pixels.

9. A method for assigning properties to an image or a video sequence in a video space-time volume, the method comprising:
-
displaying an unsegmented frame of a video sequence video space-time volume; marking by a user to use a computer selection tool during successive iterations for marking a respective single area in a region of the unsegmented frame by a single scribble covering a plurality of pixels, so as to assign at least one property to the pixels in said area; computing at each iteration respective properties of pixels in the video sequence, given the properties of the pixels in the marked area and given the computed result at a previous iteration; and displaying the video sequence so as to highlight at least one of the computed properties. - View Dependent Claims (10, 11, 12, 13)

14. A system (30) for assigning properties to an image or a video sequence, the system comprising:
-
a marking tool (33) to allow a user to mark by a single scribble during successive iterations a respective single area in a region of an unsegmented image or in an unsegmented video sequence in a a video space-time volume spanning more than a single pixel, so as to assign properties to the pixels in said area; a computational unit (31) responsive to the properties of the marked area and to an additional input constraint for computing at each iteration respective properties of pixels in the unsegmented image or the unsegmented video and segmenting the unsegmented image or an unsegmented frame of the unsegmented video sequence in accordance with the respective properties; and a display unit (36) coupled to the computational unit for displaying the image or video. - View Dependent Claims (15, 16, 17, 18, 19, 20)
