Method and apparatus for segmenting object in image
First Claim
Patent Images
1. A method of segmenting an object in a first image, the method comprising:
- obtaining the first image including the object;
receiving a first input signal including first information about a first position in the first image;
selecting at least one pixel included in the first image, based on the first information about the first position;
generating, using the selected at least one pixel, a second image by dividing the first image into several areas including a first area as a foreground area, a second area as a possible foreground area, a third area as a background area, a fourth area as a possible background area, and a fifth area as an unknown area;
regenerating the second image based on a user input by refining each of the several areas; and
segmenting the object in the first image by using the first image and the second image.

Abstract
An object in a first image is segmented by obtaining the first image including the object; receiving a first input signal including first information about a first position in the first image; selecting at least one pixel included in the first image, based on the first information about the first position; generating a second image by dividing the first image into several areas, using the selected at least one pixel; and segmenting the object in the first image by using the first image and the second image.

18. A non-transitory computer readable recording medium having embodied thereon a program for executing a method comprising the steps of:
-
obtaining a first image including the object; receiving an input signal including information about a position in the first image; selecting at least one pixel included in the first image, based on the information about the position; generating, using the selected at least one pixel, a second image by dividing the first image into several areas including a first area as a foreground area, a second area as a possible foreground area, a third area as a background area, a fourth area as a possible background area, and a fifth area as an unknown area; regenerating the second image based on a user input by refining each of the several areas; and segmenting the object in the first image by using the first image and the second image.

19. An apparatus for segmenting an object in a first image, the apparatus comprising:
-
an interface configured for obtaining the first image including the object and receiving an input signal including information about a position in the first image; an image generator configured for selecting at least one pixel included in the first image, based on the information about the position, generating, using the selected at least one pixel, a second image by dividing the first image into several areas including a first area as a foreground area, a second area as a possible foreground area, a third area as a background area, a fourth area as a possible background area, and a fifth area as an unknown area, and regenerating the second image based on a user input by refining each of the several areas; and a segmentor configured for segmenting the object in the first image by using the first image and the second image.
