Abstract
An apparatus for extracting a person region based on a red/green/blue-depth (RGB-D) image includes a data input unit configured to match an input RGB image and depth image and output matched RGB-D image data, a region-of-interest (ROI) extractor configured to remove a background image from the matched RGB-D image data from the data input unit, extract an approximate region of a person from an image obtained by removing the background image, and extract an ROI by applying a preset three-dimensional (3D) human model to the approximate person region, a depth information corrector configured to analyze the degree of similarity between the matched RGB image and depth image for the ROI extracted by the ROI extractor and correct the depth image, and a person region extractor configured to extract a person region from the depth image corrected by the depth information corrector.
