INFLUENCE OF THE OBJECT ROTATION ANGLE ON THE 3D IMAGES QUALITY

Abstract

The article presents the results of a study the accuracy of three-dimensional representation the object “Head”, which was described by a triangulated mesh and destined for transmission in a television system. There were used several variants of the three-dimensional wavelet transforms for the purpose of the mesh vertices data compression. In particular, we studied the following transforming types: Daubechies 4, Wavelet Coiflets 2, Symlets 4, Discrete Meyer, Biorthogonal 2.4, Biorthogonal 4.4. There are given the coefficients of the wavelet decompositions of triangulated mesh of the object in the horizontal, vertical and diagonal directions to the axes X, Y, Z. We obtained the dependence the error representation of three-dimensional coordinates of the mesh object “Head” from the rotation around an arbitrary axis relative to the center coordinate and the application of wavelet transforms of different types. We have defined threshold signal-to-noise ratio, which allow restoring the coordinates with a predetermined acceptable margin of error.
