A regularized nonlinear diffusion approach for texture image denoising
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...
Application of UTHSCSA-Image ToolTM to estimate concrete texture
The texture of concrete blocks is very important and is often the decisive factor when choosing a product, particularly if the building specifications does not dispense with the high resistance of the blocks, but has the ...
Plant species identification using multi-scale fractal dimension applied to images of adaxial surface epidermis
This paper presents the study of computational methods applied to histological texture analysis in order to identify plant species, a very difficult task due to the great similarity among some species and presence of ...
On the efficacy of texture analysis for crowd monitoring
(Institute of Electrical and Electronics Engineers (IEEE), Computer Soc, 1998-01-01)
The goal of this work is to assess the efficacy of texture measures for estimating levels of crowd densities ill images. This estimation is crucial for the problem of crowd monitoring. and control. The assessment is carried ...
Characterization of texture in image of skin lesions by support vector machine
Due to the increased incidence of skin cancer, computational methods based on intelligent approaches have been developed to aid dermatologists in the diagnosis of skin lesions. This paper proposes a method to classify ...

BoWFire: detection of fire in still images by integrating pixel color and texture analysis
(Universidade Federal da Bahia - UFBAIntelligent Vision Research Lab - iVisionSalvador, 2015-08)
Emergency events involving fire are potentially harmful, demanding a fast and precise decision making. The use of crowdsourcing image and videos on crisis management systems can aid in these situations by providing more ...
Applying texture-spectrum features for lung-CAD purposes
(Fundação Getulio Vargas - FGVEscola de Matemática Aplicada - EMApRio de Janeiro, 2014-08)
In this paper we propose using Texture Spectrum (T-Spec) as the feature extractor method component for Computer-Aided Diagnosis systems, particularly regarding medical lung images. We claim that employing T-Spec for this ...
Vermiculite ore classification by texture analysis
(Universidade Federal Fluminense (UFF)Rio de Janeiro, 2013)
In this paper, two micro-patterns descriptors are evaluated in the vermiculite ore classification: the Local Binary Pattern (LBP) and the Local Fuzzy Pattern (LFP). A micro-pattern is the gray-level pixels’ structure in ...
