چکیده

A new multiresolution wavelet model is presented here, which accounts for brightness assimilation and contrast effects in a unified framework, and includes known psychophysical and physiological attributes of the primate visual system (such as spatial frequency channels, oriented receptive fields, contrast sensitivity function, contrast non-linearities, and a unified set of parameters). Like other low-level models, such as the ODOG model [Blakeslee, B., & McCourt, M. E. (1999). A multiscale spatial filtering account of the white effect, simultaneous brightness contrast and grating induction. Vision Research, 39, 4361-4377], this formulation reproduces visual effects such as simultaneous contrast, the White effect, grating induction, the Todorović effect, Mach bands, the Chevreul effect and the Adelson-Logvinenko tile effects, but it also reproduces other previously unexplained effects such as the dungeon illusion, all using a single set of parameters.

Adopting the Multiresolution Wavelet Analysis in Radial Basis Functions to Solve the Perona-Malik Equation

Wavelets and radial basis functions (RBF) have ubiquitously proved very successful to solve different forms of partial differential equations (PDE) using shifted basis functions, and as with the other meshless methods, they have been extensively used in scattered data interpolation. The current paper proposes a framework that successfully reconciles RBF and adaptive wavelet method to solve the ...

Multiresolution Model Compression Using 3-D Wavelets

Three-dimensional (3-D) objects are often represented by geometric models in applications dealing with virtual reality, augmented reality, and cyberspace. Surface representations can provide an effective visualization of these objects. Polygonal models are the most prevalent type of surface representation. Recently, multiresolution representation (surface simplification) of polygonal models has...

Sound Texture Synthesis with Hidden Markov Tree Models in the Wavelet Domain

In this paper we describe a new parametric model for synthesizing environmental sound textures, such as running water, rain, and fire. Sound texture analysis is cast in the framework of wavelet decomposition and multiresolution statistical models, that have previously found application in image texture analysis and synthesis. We stochastically sample from a model that exploits sparsity of wavel...

Multiscale Likelihood Analysis and Complexity Penalized Estimation

We describe here a framework for a certain class of multiscale likelihood factorizations wherein, in analogy to a wavelet decomposition of an L function, a given likelihood function has an alternative representation as a product of conditional densities reflecting information in both the data and the parameter vector localized in position and scale. The framework is developed as a set of suffic...
