Arithmetically Fast Position Transformation for View Synthesis and Depth Estimation
In this paper we present a method of fast computation of matrix transformation in the process of position transformation of objects of the scene between different, virtual or real, camera positions. The process finds extensive use in virtual view generation in Free Viewpoint Video (FVV) and virtual...

| description | In this paper we present a method of fast computation of matrix transformation in the process of position transformation of objects of the scene between different, virtual or real, camera positions. The process finds extensive use in virtual view generation in Free Viewpoint Video (FVV) and virtual reality applications as well as in depth estimation algorithms. The proposed method relies on the reformulation of the matrix equation used in the process. As a result, the number of necessary arithmetic operations is reduced and some of the calculations can be reused for consecutive pixel position transformations. The presented algorithm produces identical output as an unoptimized algorithm with approximately 22% reduction of the processing time averaged over the examined representative test sequences. |
