T. Beach, P. Gibbs, M. D. Pickles, L. Turnbull Centre for MR Investigations, University of Hull, Hull, United Kingdom Introduction Quantitative textural analysis is an established method of image classification in aerial and satellite photography. In recent years attempts have been made to utilise texture in MRI, particularly in the brain [1-6], but also in other organs such as breast [7] and l...

RATIONALE Timely detection of pseudoprogression (PSP) is crucial for the management of patients with high-grade glioma (HGG) but remains difficult. Textural features of O-(2-[18F]fluoroethyl)-L-tyrosine positron emission tomography (FET-PET) mirror tumor uptake heterogeneity; some of them may be associated with tumor progression. METHODS Fourteen patients with HGG and suspected of PSP underwe...

In this article we describe specific methods for the characterization and computer assisted diagnosis of some severe abdominal diseases, based on ultrasound images and the corresponding software system. The objective of our research is to build an instrument for the non-invasive diagnosis, based on virtual biopsy, of some severe abdominal diseases such as the cirrhosis, the hepatocellular carci...

nicotine is an alkaloid by high level of addictive property that can quickly assimilate from smoker’s lung. it passes from the placenta and gathers in the developing fetus. our previous study showed that collagen type iv plays a critical role in basement membrane of different embryonic organs. in this study the effect of maternal nicotine was evaluated by collagen iv changes in lung of mice off...

Porous organic–inorganic materials with tunable textural characteristics were synthesized using the topdown process by intercalating silsesquioxanes and polyhedral oligomeric siloxanes of different types between crystalline zeolite-derived layers. The influence of key parameters such as (i) linker nature (pure hydrocarbon, S-, N-containing); (ii) chain length in alkyland aryl bis(trialkoxysilyl...

Gravel-free, high-resolution (1-metre spacing, 32 channel) particle size data from the CRP-2/2A drill core indicate that many of the diamictites were likely deposited from floating ice. Textural dislocations occur at most sequence boundaries and provide independent corroboration of the sequence stratigraphic interpretation. Likewise the data largely support the correlation drawn (Fielding et al...

melissa officinalis l. (labiatae) traditionally used in treating neurological disorders has also been identified as a memory-enhancing herb. the extract of m. officinalis has a cholinergic property. the role of basal forebrain cholinergic neurons, the neurons that are destroyed in alzheimer’s disease (ad), in learning and memory, is also well known. the aim of this study is to investigate the r...

We provide a thorough experimental evaluation of several state-of-the-art textural features on four representative and extensive image databases. Each of the experimental textural databases ALOT, Bonn BTF, UEA Uncalibrated, and KTH-TIPS2 aims at specific part of realistic acquisition conditions of surface materials represented as multispectral textures. The extensive experimental evaluation pro...
