1. Global and Local Oriented Gabor Texture Histogram for Person Re-identification
ABSTRACT: Automated person re-identification is a key process in global distributed camera systems. This paper proposes a new feature, the Global and Local-Oriented Gabor Texture Histogram (GLOGTH), for person re-identification. GLOGTH is a combination of the local texture and global structure information of a given input image. This feature aims at represen

2. Carbon Stocks and Pools in Relation to the Texture of Kaolinitic Soils from the Brazilian East Coast
ABSTRACT: Extremely kaolinitic soils of Tertiary age elevations on the Brazilian east coast present a wide range of texture, which is recognized as one of the main factors controlling the soil organic matter contents. This study aimed to investigate the organic C storage of different compartments of kaolinitic soils. The studied soils had a wide particle siz

3. Poaceae communities in the savannas of the Amazon Estuary in Brazil
We sought to identify the major environmental factors that affect the diversity and distribution of Poaceae in the savannas of the Amazon Estuary. The study was conducted across seven areas of savanna in the Amazon Estuary, within which 160 subplots of 1 m² each were established within four 10 × 100 m plots. Soil samples were collected at a depth of 0-20 c

4. Tamanhos pictóricos percebidos sobre gradientes de textura desenhados e fotografados após exposições breves / Pictorial size perceived under line-drawing and photographed texture gradient after brief exposures
O presente estudo teve por objetivo investigar a dinâmica temporal da percepção de tamanho de objetos inseridos em gradientes de textura, provenientes de desenho gerado computacionalmente (gradiente de perspectiva) e de fotografia com elementos naturais (gradiente fotografado). Além disso, verificou-se a ocorrência e padrão dos movimentos oculares nest

5. Soil profile, relief features and their relation to structure and distribution of Brazilian Atlantic rain forest trees
In tropical forests, the environmental heterogeneity can provide niche partitioning at local scales and determine the diversity and plant species distribution. Thus, this study aimed to investigate the variations of tree species structure and distribution in response to relief and soil profile features in a portion of the largest remnant of Brazilian Atlanti

6. O efeito do solo, inundação e topografia sobre as campinaranas inundáveis na Amazônia
Little is known about the factors that determine the spatial variation in structure, floristic composition and diversity in the Amazon Campinaranas. The Campinaranas are characterized by predominantly oligotrophic sandy soils. In the Negro River basin, they occur in a mosaic of grassland formations, forest and savanna, often associated with flooding. To infe

7. Stochastic texture image estimators for local spatial anisotropy and its variability
A new image analysis technique is proposed for the evaluation of local anisotropy and its variability in stochastic texture images. It utilizes the gradient function to provide information on local anisotropy, from two-dimensional (2-D) density images for foil materials like polymer sheets, nonwoven textiles, and paper. Such images can be captured by radiogr

8. Stochastic texture analysis for measuring sheet formation variability in the industry
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among such industrial stocha

9. Hydrophobicity classification in high voltage polymeric insulators / Classificação da hidrofobicidade em isoladores elétricos poliméricos de alta tensão
The aim of this study is to propose a new method to classify the hydrophobicity (HC) in high voltage polymer insulators. Currently the HC is based on the STRI guide (Swedish Transmission Research Institute) published in 1992, where the hydrophobicity is classified by contact angle and/or amount of wet surface. In the proposed method, the HC was analyzed by d

10. Influence of the distance of installation of tensiometers to calculate total potential gradient in the field soil hydraulic conductivity determination / Influência da distância de instalação de tensiômetros no campo para o cálculo do gradiente de potencial total no método do perfil instantâneo
The soil hydraulic conductivity determination method most used under unsaturated field conditions is the instantaneous profile method. This method is based on the integration of Richards equation in relation to soil depth, during the soil water redistribution process, after the profile has been saturated till the interest depth and the soil surface prevented

11. Caracterização de solos em uma topoclimossequência no maciço de Triunfo - Sertão de Pernambuco / Characterization of soils along a topoclimosequence in Triunfo mountain-semi-arid of Pernambuco state
High altitude forest in mountain of Northeast Brazil are islands of the Humid Atlantic forest in the middle of semi-arid region, with an atypical climatic condition, improved by the occurrence of orographic precipitions that can reach more than 1200mm per year. In Pernambuco state scientific studies in these humid sites were only related to botanic and biolo

12. Comparações de tamanhos sob informações pictóricas de profundidade provenientes de gradientes de textura e horizonte em exposições breves / Size comparisons under effects of pictorial depth cues from texture gradient and horizon in brief exposures.
The aim of this study was to investigate the effects of the duration of pictorial depth cue exposures on perceived sizes of stimuli. For this, 120 volunteers distributed randomly in 12 groups compared two vertical bars, one the test and other the standard, in to order to report which one was bigger. Using the method of constant stimuli, these bars could be p
