摘要： A method estimates a 3D pose of a 3D specular object in an environment. In a preprocessing step, a set of pairs of 2D reference images are generated using a 3D model of the object, and a set of poses of the object, wherein each pair of reference images is associated with one of the poses. Then, a pair of 2D input images are acquired of the object. A rough 3D pose of the object is estimated by comparing features in the pair of 2D input images and the features in each pair of 2D reference images using a rough cost function. The rough estimate is optionally refined using a fine cost function.

摘要： A method for converting an image in an image conversion apparatus is provided. The method includes receiving a stereo image, down-scaling the stereo image, performing stereo-matching by applying adaptive weight to the down-scaled stereo images, generating a depth map according to the stereo-matching, up-scaling the depth map by referring to an input image of original resolution, and generating a plurality of multi-view images by performing depth-image-based rendering with respect to the up-scaled depth map and the input image of original resolution. Accordingly, a plurality of multi-view images may be obtained with ease.
