This paper presents a new texture analysis method based on structural properties. The texture features extracted using this algorithm are invariant to affine transform (including rotation, translation, scaling, and skewing). Affine invariant structural properties are derived based on texel areas. An area-ratio map utilizing these properties is introduced to characterize texture images. Histogra...

We presented in 2008 the initial steps of our project, to use Blender for scientific representation and molecular animation of life at the cellular level. This report will focus on some developments in two major aspects: the use of Blender Game Engine in conjunction with other scientific programs to elaborate the movement of proteins and the development of a visual code based on texturing and p...

To investigate and control quality, one must be able to measure quality-related attributes. Quality of produce encompasses sensory attributes, nutritive values, chemical constituents, mechanical properties, functional properties and defects. Instrumental measurements are often preferred to sensory evaluations in research and commercial situations because they reduce variations in judgment among...

tomato is one of the sensitive fruits to mechanical impacts and physical tensions. the mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 j by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety shiva f1, includingripening factor...

Textural features are one of the most important types of useful information contained in images. In practice, these features are commonly masked by noise. Relatively little attention has been paid to texture preserving properties of noise attenuation methods. This stimulates solving the following tasks: (1) to analyze the texture preservation properties of various filters; and (2) to design ima...

Functionality of Marve seed gum (Salvia Macrosiphon Boiss) on rheological properties and staling of Baguette bread have been studied. Three different concentrations of 0.1 %, 0.5% and 1% (w/w, flour basis) were applied and this hydrocolloid affected the quality of the stored bread to some extent. The effects of Marve seed gum on the rheological properties of dough was also investigated instrume...

In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of welds. Also, vibrational sample magnetometry was used for characterizing magne...

A novel approach to visually represent perceptual features of textures is proposed and analysed. This approach combines statistical properties of the texture together with qualitative measures coming from human perception. Quantitative measures, coming from co-occurrence analysis, have been in turn visually represented using an effective iconic representation, producing an immediate and easy to...

Echocardiography is the predominant technique for quantitative assessment of cardiac function. This paper presents a new noise resistive method for segmenting echocardiographic images using fuzzy logic and texture properties. In echocardiographic images, the transition between blood pool and myocardium is significant, which reflects as variations in texture properties. Our edge detection method...

Graded ditopological texture spaces have been presented and discussed in categorical aspects by Lawrence M. Brown and Alexander {v S}ostak in cite{BS}. In this paper, the authors generalize the structure of diuniformity in ditopological texture spaces defined in cite{OB} to the graded ditopological texture spaces and investigate graded ditopologies generated by graded diuniformities. The autors...
