APPARATUS FOR REPRESENTING THREE-DIMENSIONAL OBJECT MOTION WITH SEMIREGULAR MESHES

摘要

The present invention relates to a quasi-uniform mesh representation of three-dimensional objects moving device, the input mesh of the object's motion and the intra-rime swingbu converting gave a uniform mesh with an algorithm to perform the quasi-uniform mesh of the screen mesh with respect to the 3D still the first mesh in the sequence, and a frame memory for storing the converted quasi-uniform mesh by rime swingbu, and quasi-uniform mesh information of the neighboring frames stored in the frame memory, the global motion is calculated and the calculation of the global motion between the base mesh of the two frames using neighboring the base mesh of each frame of the input mesh between the current frame sequence calculation of the motion prediction using the ICP algorithm, the previous frame stored in the frame memory by using a higher-level vertex information and local transformation between the two frames of the transform form the base mesh to obtain a high-level vertex position of the current frame, by the type transformation correction to convert the distorted area with optional quasi-uniform mesh screen area and can not perform a quasi-uniform expression in the form of a geometric transformation of the type conversion is severely distorted with respect to the two frame parts may appear between the side length and the angle of the triangle area, and the like the found base triangle as parameterized by mapping vertices of the original mesh for the compensation of damage changes taking cover a large part through the comparison, and by the type of conversion and, quasi-uniform mesh representation of still using the parameterized information Applying the techniques, including a re-meshing inter effectively representing a quasi-uniform mesh with selective quasi-uniform mesh with zoning expression selectively re-meshing process possible. Thus, through the quasi-uniform three-dimensional network mesh representation scheme may obtain a quasi-uniform representation of the video, may be applied to signal processing techniques, such as applying the interpolation through the corresponding points between neighboring frames, the encoding through the Zune uniform expression there is an effect that it is possible to maximize performance.
