Partition of unity parametrics for texture synthesis
نویسندگان
چکیده
Partition of unity parametrics (PUPs) are a recent framework designed for geometric modeling. We propose employing PUPs for procedural texture synthesis, taking advantage of the framework’s guarantees of high continuity and local support. Using PUPs to interpolate among data values distributed through the plane, the problem of texture synthesis can be approached from the perspective of point placement and attribute assignment. We present several alternative mechanisms for point distribution and demonstrate how the system is able to produce a variety of distinct classes of texture, including analogs to cellular texture, Perlin noise, and progressivelyvariant textures.

متن کاملA Subdivision Framework for Partition of Unity Parametrics
Partition of Unity Parametrics (PUPs) are a generalization of NURBS that allow us to use arbitrary basis functions for modeling parametric curves and surfaces. One interesting problem is finding subdivision schemes for this recently developed and flexible class of parametrics. In this paper, we introduce a systematic approach for determining uniform subdivision of PUPs curves and tensorproduct ...
متن کاملA fast, discrete Gabor transform via a partition of unity
A partition of unity on the d-dimensional integer lattice Z is used to create a generalized discrete Gabor transform, with analysis and synthesis windows of smooth, desirable characteristics. Factorizing the partition of unity allows for different choices of analysis and synthesis windows, a transformation on general lattices in the time and frequence domains is considered, and an approximate p...
متن کاملA Texture Synthesis Method Based on Multi-resolution Matching
Texture synthesis is the field of computer graphics and related basic core issues. Studies have shown that the MRF model-based two-dimensional image texture synthesis algorithm, the synthesis results are directly affected by the magnitude of the impact of random images; that is consistent with a high degree of MRF model is better than other texture synthesis texture. The same time, the quality ...
متن کاملMultiscale Enrichment based on Partition of Unity
A new Multiscale Enrichment method based on the Partition of Unity (MEPU) method is presented. It is a synthesis of mathematical homogenization theory and the Partition of Unity method. Its primary objective is to extend the range of applicability of mathematical homogenization theory to problems where scale separation may not be possible. MEPU is perfectly suited for enriching the coarse scale...
