We analysed the temporal-frequency characteristics of two functional processes involved in orientation-based texture segregation: local orientation coding and subsequent orientation-contrast coding. Two texture images, in which each micropattern was rotated by 90 degrees, were alternated at various temporal frequencies. A micropattern was a second-derivative (D2) of a Gaussian that loses orient...

the fire as one of the ecological factor has positive or negative effects on ecosystems components. therefore, this study was evaluated the effect of fire on some soil physico-chemical properties in winter rangelands of behshahr. so that two burned sites were selected in rangelands and changed rangelands to wheat and barley with two control areas (unburned) in each of them. the soil sampling wa...

Pb(ZrxTi1-x)O3 [PZT] thin films of morphotropic phase boundary (MPB) composition having {001}, {110}, and {111}orientations were fabricated on silicon substrates (111)Pt/Ti/SiO2/Si using a metal organic decomposition spin-coating technique. The influence of crystallographic orientation on the transverse piezoelectric coefficient e31 * of the films have been determined. The largest e31 * was fou...

ripening is one of the most important stages in production of cheese. in this research to comprehensive study of uf cheese ripening as the major industrial cheese that is produced in iran, mass transfer, heat transfer and changes in quality and sensory properties, simultaneously considered and a mathematical model was developed to describe them. thus, at first, lipolysis, proteolysis, texture a...

in this study, potential application of image texture analysis as a non-destructive method for automation and prediction of mechanical properties of carrot chips was investigated. samples were fried at different processing conditions and moisture content, colour parameters (i.e. l*, a*, b* and e) and mechanical properties (i.e. hardness and apparent modulus) were determined. hardness and appar...

The object of research is fish culinary products in the jelly pouring menu conceptual restaurants. subject consumer characteristics gelling broth for based on sensory characteristics. study used methods determining physical, chemical, aesthetic and analysis. Methods preliminary preparation hydrocolloids as structure-forming agents with parameters formation process are proposed. developed ingred...

In this thesis we propose a standardized method for extracting illumination-invariant images and a novel approach for classifying textures. Experiments are also extended to include object classification using the proposed methods. The illumination-invariant image is a useful intrinsic feature latent in color image data. Existing methods of extracting the invariant image are dependent upon the c...

Probiotic fermented sausages are safe and healthy meat products. Semi-dry fermented sausages were manufactured from camel meat inoculated with Lactobacillus casei and Lactobacillus paracasei and control. All treatments were analyzed for the  physico-chemical characteristics (Protein, Moisture, Fat, Ash, Lactic acid value and pH), microbiological features (total aerobic, total mold and yeast...
