A Shape-Aware Model for Discrete Texture Synthesis
نویسندگان
چکیده
We present a novel shape-aware method for synthesizing 2D and 3D discrete element textures consisting of collections of distinct vector graphics objects. Extending the long-proven point process framework, we propose a shape process, a novel stochastic model based on spatial measurements that fully take into account the geometry of the elements. We demonstrate that our approach is well-suited for discrete texture synthesis by example. Our model enables for both robust statistical parameter estimation and reliable output generation by Monte Carlo sampling. Our numerous experiments show that contrary to current state-of-the-art techniques, our algorithm manages to capture anisotropic element distributions and systematically prevents undesirable collisions between objects.

λ((u,s);x)= f (x) f (x\(u,s)) if (u,s) is one of the elements of x, f (x∪(u,s)) f (x) otherwise. (A) Evaluating this conditional intensity λ efficiently is thus a critical requirement. One should stress that the ratios f (x\(u,s)) f (x) and f (x∪(u,s)) f (x) are of course not computed directly but after simplification of the many common terms that are on both sides of the fractions.

متن کاملProbabilistic Discrete Mixtures Colour Texture Models
A new generative multispectral texture model based on discrete distribution mixtures is introduced. Statistical texture properties are represented by a discrete distribution mixture of product components. A natural colour or multispectral texture is spectrally factorized and discrete mixtures models are learned and used to synthesize single orthogonal monospectral components. Texture synthesis ...

1 A variety of natural and man-made phenomena can be characterized 2 by repetitive discrete elements. Examples include a stack of fruits, 3 a plate of dish, or a stone sculpture. Although certain results can 4 be produced via existing methods based on procedural or physical 5 simulation, these are often designed for specific applications. Some 6 of these methods can also be hard to control. 7 W...
متن کاملPose-Invariant Face Recognition: Representing Known Persons by View-based Statistical Models
We present a framework for pose-invariant face recognition using parametric linear subspace models as stored representations of known individuals. Each model can be t to an input, resulting in faces of known people whose head pose is aligned to the input face. The model's continuous nature enables the pose alignment to be very accurate, improving recognition performance, while its generalizatio...
