In this paper we evaluate two statistical approaches to semi-automated texture enhancement and discrimination for landslide mapping in semi-arid, sedimentary terrain from Daedalus ATM data. A supervised texture discrimination technique is applied, based on calculating similarity between a reference texture spectrum obtained from training samples and spectra from moving image windows. The result...
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 b...
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 nucleoside analog 3'-deoxy-3'F-fluorothymidine (FLT) has been investigated for evaluating tumor proliferating activity in brain tumors. We evaluated FLT uptake heterogeneity using textural features from the histogram analysis in patients with newly diagnosed gliomas and examined correlation of the results with proliferative activity and patient prognosis, in comparison with the conventional...
With the growth of technology, supervising systems are increasingly replacing humans in military, transportation, medical, spatial, and other industries. Among these systems are machine vision systems which are based on image processing and analysis. One of the important tasks of image processing is classification of images into desirable categories for the identification of objects or their sp...
