Abstract: A method and apparatus for image warping are provided. The image warping apparatus comprises a shielded area management unit for generating shielded area information based on a stereo source image; and an image processing unit which interpolates variations of the shielded area information based on rare variation information of the stereo source image, and separates a shielded area and a non-shielded area when mesh warping the stereo source image to generate a virtual intermediate viewpoint image by using the result of the shielded area information reconstruction according to the variation-interpolated shielded area information.

Abstract: The present invention relates to a stereo image processing method and, more specifically, to an image processing method for filtering an occlusion area in a stereo image. The method comprises the following steps of: calculating an optical flow based disparity from a stereo image; obtaining feature point based disparity saliency from the stereo image; generating a disparity saliency map based on the calculated optical flow disparity (saliency) and the feature point based disparity saliency; and filtering an occlusion area on the disparity saliency map. In the step of filtering an occlusion area on the disparity saliency map, a disparity is once calculated based on one side of the stereo image and a disparity is calculated again based on the other side of the stereo image. If a difference between two disparities of a particular pixel is greater than a given limit, the particular pixel is detected as an occlusion area pixel, and the disparity value of the particular pixel on the disparity saliency map is corrected to have a minimum value among disparity values between the particular pixel and adjacent pixels.

Abstract: PURPOSE: An apparatus and a method for reconstructing an intermediate view are provided to process border noise generated by intermediate image synthesis. CONSTITUTION: An image acquisition unit(110) obtains two or more multi-view reference images filmed at various points of time. A three dimensional conversion unit(120) warps the obtained reference image three-dimensionally. The three dimensional conversion unit synthesizes an intermediate image. An intermediate image compensation unit(200) removes boundary noise or common hole generated from the intermediate image. A boundary noise processing unit(210) detects/removes only the boundary noise.
