Fractal-based image coders suuer from perceptually annoying distortion in textured areas. This paper discusses possible reasons for this limitation. A texture may be modelled as a stochastic process with place-independent autocorrelation properties. Two image areas should have similar correlation (spectral) properties to be perceived as belonging to the same texture. We show that stationary tex...

The present study was undertaken to develop a modified texture analysis algorithm based on the properties of texture spectrum (TS) domain for the satellite images. In texture analysis some specific spatial filters are required, which can transform the image based on the textural features instead of changing the spectral properties; the image is thus characterized by its texture spectrum. This p...

Studies were conducted to evaluate the combined effects of spontaneous fermentation and amylase-rich flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2 x 3 x 3 factorial design, with fermentation medium, fermentation time and ARF level, was performed. The blends were fermented for the specific times and analysed for their tit...

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...
