Abstract: An image processing method includes: selecting frames from an input image sequence, wherein the selected frames include a first frame and a second frame; generating a polygon mesh including polygons for each of the selected frames using feature points having depth values, among feature points of each of the selected frames; setting a search range of a corresponding pixel of the second frame corresponding to a pixel of the first frame based on the polygon mesh; and estimating a depth value of the pixel of the first frame by matching the pixel of the first frame and the corresponding pixel based on the search range.

Abstract: A stereo matching method includes extracting feature points of a first image and feature points of a second image, the first image and the second image together constituting a stereo image, determining reference points by matching the feature points of the second image to the feature points of the first image, classifying the reference points, and performing stereo matching on pixels of which disparities are not determined in the first image and the second image based on disparities of the reference points in the pixels determined based on a result of the classifying.

Abstract: Provided is a stereo matching method and apparatus. A stereo matching method includes acquiring detection information based on an edge detection of a first image, determining an edge line and a feature point based on the detection information, sampling a reference pixel from the edge line and the feature point, determining a polygon with the reference pixel as a vertex, predicting a search range comprising a disparity of a pixel within the polygon based on a disparity of the reference pixel, and performing stereo matching of the pixel based on the search range.

Abstract: A shadow information storing method and apparatus is disclosed. The shadow information storing apparatus determines a shadow area through rendering a three-dimensional (3D) model based on light radiated from a reference virtual light source, determines a shadow feature value of a vertex of the 3D model based on a distance between a location of the vertex of the 3D model and the shadow area, and stores the determined shadow feature value.
