چکیده
Abstract Procedural noise functions are fundamental tools in computer graphics used for synthesizing virtual geometry and texture patterns. Ideally, a procedural function should be compact, aperiodic, parameterized, randomly accessible. Traditional lattice such as Perlin noise, however, exhibit periodicity due to the axial correlation induced while hashing vertices gradients. In this paper, we introduce parameterized called prime gradient (PGN) that minimizes discernible enhancing algorithmic efficiency. PGN utilizes gradients, set of random unit vectors constructed from subsets numbers plotted polar coordinate system. To map indices employs Szudzik pairing, bijection F : ℕ 2 → ℕ. Compositions pairing higher dimensions. At core is ability parameterize generation though sequence offsetting which facilitates creation fractal with varying levels heterogeneity ranging homogeneous hybrid multifractals. A comparative spectral analysis proposed other noises including show significantly reduces hence, texture. We demonstrate utility several examples modeling, pattern synthesis, solid texturing.

Better Gradient Noise
We present three improvements to Perlin’s gradient noise algorithm. First, a small change in the permutation hash function combined with separate pseudorandom tables yields significantly better axial decorrelation. Second, a modification to the reconstruction kernel approximating a global higher-order differencing operator produces better bandlimitation. Third, the quality of 2D surfaces using ...
متن کاملConvergence properties of gradient descent noise reduction
Gradient descent noise reduction is a technique that attempts to recover the true signal, or trajectory, from noisy observations of a non-linear dynamical system for which the dynamics are known. This paper provides the first rigorous proof that the algorithm will recover the original trajectory for a broad class of dynamical systems under certain conditions. The proof is obtained using ideas f...
متن کاملActive noise barrier minimizing pressure gradient
Active noise barrier minimizing pressure gradient" (2010). Architectural Engineering-Faculty Publications. 96. Minimization of the sound pressure field within the shadow zone of a noise barrier is achieved by reducing the pressure gradient along a line, at the top of a barrier, via active noise control. The noise control effectiveness of a barrier is increased by this strategy, especially for s...
متن کاملAcoustic Noise Suppression: Gradient Self-Help?
Recently, Tomasi and Ernst introduced a simple string model for understanding the vibrations of MRI gradient coils. [1] We build upon this simple foundation to provide a window into a particular method for active noise cancellation, where the pulse sequences that caused the problem may be designed to solve the problem. Previous work has focused on active and passive shielding to control eddy cu...
متن کاملAn Intelligent Anti-Islanding Scheme for Synchronous-Based Distributed Generation Using Reduced-Noise Morphological Gradient
This paper presents a pattern recognition-based scheme for detection of islanding conditions in synchronous- based distributed generation (DG) systems. The main idea behind the proposed scheme is the use of spatial features of system parameters such as the frequency, magnitude of positive sequence voltage, etc. In this study, the system parameters sampled at the point of common coupling (PCC) w...
