The present invention relates to a 2D image segmentation apparatus and method, and apparatus and method for removing red eye from image. A Two-Dimensional (2D) image segmentation apparatus for segmenting pixels of a progressive input 2D image includes a group information storing unit storing information of pixel groups including a plurality of adjacent pixels; a pixel determining unit determining coordinates of an input pixel, and determining whether the input pixel is an effective pixel for segmentation; a group scanning unit scanning a adjacent pixel group disposed in a scan range preset from the effective pixel in the group storing unit when the input pixel is determined as the effective pixel by the pixel determining unit; and a group information updating unit updating information of a pixel group stored in the group information storing unit according to whether there is the scanned adjacent pixel group and a pixel group including an input pixel preceding the effective pixel. Moreover, a method is provided that removes red-eye using area information of a pixel group determined by the segmentation apparatus.
Description
[0001] This application claims the benefit of Korean Patent Application No. 2008-21236 filed on March 7, 2008 with the Korean Intellectual Property Office and Korean Patent Application No. 2008-44444 filed on May 14, 2008, the disclosure of which is fully Incorporated here for reference. technical field [0002] The present invention relates to the field of digital image processing, and more particularly, to a two-dimensional (2D) image segmentation device and method for segmenting pixels of a progressively input image to detect a specific pattern of the image, and a method for removing red eyes in a segmented area Apparatus and method for removing red eye in 2D images. Background technique [0003] Recently, pattern recognition technology that recognizes specific shapes through image processing has been applied to various industrial fields. Examples of the pattern recognition technology include known pattern recognition technologies such as a pattern recognition system tha...
