    摘要: Provided is a camera motion estimation method and apparatus that may estimate a motion of a depth camera in real time. The camera motion estimation apparatus may extract an intersection point from plane information of a depth image, calculate a feature point associated with each of planes included in the plane information using the extracted intersection point, and extract a motion of a depth camera providing the depth image using the feature point. Accordingly, in an environment where an illumination environment dynamically varies, or regardless of a texture state within a space, the camera motion estimation apparatus may estimate a camera motion.

    摘要: Provided is an image processing apparatus for extracting a three-dimensional (3D) feature point from a depth image. An input processing unit may receive a depth image and may receive, via a user interface, selection information of at least one region that is selected as a target region in the depth image. A geometry information analyzer of the image processing apparatus may analyze geometry information of the target region within the input depth image, and a feature point extractor may extract at least one feature point from the target region based on the geometry information of the target region.

    摘要: A method and an apparatus search an image using a feature point. The image search method extracts at least one feature point from an image and describes the extracted at least one feature point in stages, thereby generating a hierarchical feature point descriptor. In addition, the method may search for information matching the feature point descriptor from a local database (DB) included in a terminal or a remote DB included in a server.

    摘要: A method and apparatus for expressing a rigid area based on expression control points that express a motion change of the rigid area with respect to an input expression. The method and apparatus express the rigid area by interpolating a change of expression of an avatar using a weight applied to an expression vector related to a plurality of expression samples to express the input expression and also using a transformation matrix set corresponding to the rigid area of each of the plurality of expression samples.
