A Scale-space Analysis of Multiplicative Texture Processes
نویسنده
چکیده
Gaussian Scale-space describes the local structure of images. This paper shows a stochastic analysis of the diffusion equation as put forward by Koenderink (1984) for regular images. Important classes of the stochastic process which are structurally described by the diffusion analysis include Brownian fractals, Markovian textures, and fragmentation processes. The analysis shows the diffusion coefficient to relate to the local autocorrelation function over the diffusion process. Diffusion of the multiplicative image formation process directly leads to power-law statistics over the diffusion scale, and to Weibull statistics in the spatial domain.

ADMITTING CENTER MAPS ON MULTIPLICATIVE METRIC SPACE
In this work, we investigate admitting center map on multiplicative metric space and establish some fixed point theorems for such maps. We modify the Banach contraction principle and the Caristi's fixed point theorem for M-contraction admitting center maps and we prove some useful theorems. Our results on multiplicative metric space improve and modify s...

According to the large number of geographical distribution of small se...
متن کاملThe effect of speckle filtering on scale-dependent texture estimation of a forested scene
Spatial fluctuations in microwave backscatter may be an important piece of information in discriminating tree stands. However, the presence of speckle in synthetic aperture radar (SAR) image data is a barrier to the exploitation of image texture. We explored a new methodology that combines a recent adaptive speckle reduction algorithm by Lopes et al. [12] with a generic texture estimation schem...
متن کاملExtended Geometric Processes: Semiparametric Estimation and Application to ReliabilityImperfect repair, Markov renewal equation, replacement policy
Lam (2007) introduces a generalization of renewal processes named Geometric processes, where inter-arrival times are independent and identically distributed up to a multiplicative scale parameter, in a geometric fashion. We here envision a more general scaling, not necessar- ily geometric. The corresponding counting process is named Extended Geometric Process (EGP). Semiparametric estimates are...
متن کاملScale Space Texture Classification Using Combined Classifiers with Application to Ultrasound Tissue Characterization
Texture is often considered as a repetitive pattern and the constructing structure is known as texel. The granularity of a texture, i.e. the size of a texel, is different from one texture to another and hence inspiring us applying scale space techniques to texture classification. In this paper Gaussian kernels with different variances (s ) are convolved with the textures from Brodatz album to g...
