Bilateral Blue Noise Sampling: Additional Algorithms and Applications
نویسندگان
چکیده
Blue noise sampling is an important component in many graphics applications, but most of the prior techniques consider mainly the spatial positions of samples, making them less effective when handling features, such as image color and surface geometry. We apply the bilateral blue noise dart throwing method in [Chen et al. 2013] to graphics applications including image/video stippling and nonlinear filtering. We also propose a bilateral Lloyd relaxation method which works comparably with the kernel based bilateral relaxation method in [Chen et al. 2013].

Spoke Darts for Efficient High Dimensional Blue Noise Sampling
Blue noise refers to sample distributions that are random and wellspaced, with a variety of applications in graphics, geometry, and optimization. However, prior blue noise sampling algorithms typically suffer from the curse-of-dimensionality, especially when striving to cover a domain maximally. This hampers their applicability for high dimensional domains. We present a blue noise sampling meth...
متن کاملFast adaptive blue noise on polygonal surfaces
This paper proposes a novel method for the computation of hierarchical Poisson disk samplings on polygonal surfaces. The algorithm generates a pointerless hierarchical structure such that each level is a uniform Poisson disk sampling and a subset of the next level. As the main result, given a dynamically-varying importance sampling function defined over a surface, the hierarchy is capable of ge...
متن کاملProjective Blue-Noise Sampling
Wepropose projective blue-noise patterns that retain their blue-noise characteristics when undergoing one ormultiple projections onto lower dimensional subspaces. These patterns are produced by extending existing methods, such as dart throwing and Lloyd relaxation, and have a range of applications. For numerical integration, our patterns often outperform state-of-the-art stochastic and low-disc...
متن کاملUsing Scalloped Sectors to Generate Poisson-Disk Sampling Patterns
Sampling distributions with blue noise characteristics are widely used in computer graphics. Although Poisson-disk distributions are known to have excellent blue noise characteristics, they are generally regarded as too computationally expensive to generate in real time. We present a new data structure that alllows sampling by dart-throwing in O(N logN) time. We also show how a novel and effici...
متن کاملPerformance Evaluation of Local Detectors in the Presence of Noise for Multi-Sensor Remote Sensing Image Matching
Automatic, efficient, accurate, and stable image matching is one of the most critical issues in remote sensing, photogrammetry, and machine vision. In recent decades, various algorithms have been proposed based on the feature-based framework, which concentrates on detecting and describing local features. Understanding the characteristics of different matching algorithms in various applications ...
