OBJECTIVE To determine the value of contourlet textural features obtained from solitary pulmonary nodules in two dimensional CT images used in diagnoses of lung cancer. MATERIALS AND METHODS A total of 6,299 CT images were acquired from 336 patients, with 1,454 benign pulmonary nodule images from 84 patients (50 male, 34 female) and 4,845 malignant from 252 patients (150 male, 102 female). Fu...

Knowledge of the textural properties of processing tomatoes is crucial to ensuing product acceptability; measurement, control, and optimization of these properties through judicious selection of varieties and control of unit operations results in products that the consumer prefers. It is important to first define the terms texture, rheology, consistency, and viscosity prior to discussing princi...

The relationship between textural properties of selected Nigeria rocks and penetration rate of top-hole hammer drill was investigated. These rock samples were tested in the laboratory for mineral composition, silica content and porosity. Also, average grain size and packing density were determined from photomicrograph of the samples using empirical equations proposed by researchers. Penetration...

background & aim: tragacanth is a natural gum obtained from the dried sap of several species of middle eastern egumes of the genus astragalus, that is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides. tragacanth is used in pharmaceutical and foods industries as an emulsifier, thickener, stabilizer, and texturant additive. sponge cake is one of the most popular bakery...

Image textural analysis technology has been widely used in the design of automated defect detection systems. Because the presence of defects may change the textural features of an image, a reference image without defects can be compared with the test image to detect whether there are any defects. However, besides defects, the deflection of the input test image could also change its textural fea...

This Letter describes a procedure that incorporates textural measures in the classification of logged forests from Landsat Thematic Mapper data. The objective was to increase classification accuracy by applying recently developed algorithms in machine learning that are fast in training. Three voting classification algorithms, Arc-4x, Adaboost and bagging were also tested. Initial results using ...

A novel statistical textural distinctiveness approach for robustly detecting salient regions in natural images is proposed. Rotational-invariant neighborhood-based textural representations are extracted and used to learn a set of representative texture atoms for defining a sparse texture model for the image. Based on the learnt sparse texture model, a weighted graphical model is constructed to ...

background: momordica charantia (m. charantia) seed has been supposed to have an antifertility property but mechanisms underlying the infertility effect have not been investigated. objective: we investigated the antifertility effect of m. charantia ethanol seed extracts on reproductive toxicology and seminal and plasma testosterone in male wistar rats. materials and methods: the control group (...

This paper presents a Frame Semantics analysis of calendric terms in English, Hebrew, and German, demonstrating the inextricable relationship between morphology and semantics. Here, we consider how Frame Semantics can be extended to morphological analysis. Traditionally, the morpheme has been taken as the smallest unit of meaning in linguistic analysis, with generative word formation rules gene...
