We present a new approach to a componentware development methodology based on a system of process patterns. We argue that organizing the development process by means of a pattern system results in higher flexibility compared to traditional ways of defining development processes. This is especially important in the context of componentware. Finally, we propose a pattern catalog with a selection ...

In this paper we evaluate several extensions of Local Binary Patterns to color images. In particular, we investigate their robustness with respect to changes in the illuminant color temperature. To do so, we recovered the spectral reflectances of 1360 texture images from the Outex 13 data set. Then, we rendered the images as if they were taken under 33 different illuminants. For each combinatio...

introduction drought is one of the climate risks that has made iran to be one of the 10 countries subject to drought. scientific knowledge about this phenomenon is necessary in order to plan, manage and confront with problems resulting from drought. considering the spatial extent and climate variability of iran, all climates of this country are prone to drought. due to the fact that khorasan ra...

We study, in this paper, curvature inheritance symmetry (CI), £ξR a bcd = 2αR bcd , where α is a scalar function, for string cloud and string fluid in the context of general relativity. Also, we have obtained some result when a proper CI (i.e., α 6= 0) is also a conformal Killing vector.

This paper proposes using soft histograms for the Local Binary Pattern (LBP) operator that has been widely applied in different image analysis tasks. This makes the operator more robust to noise and make its output continuous with respect to input. The proposed extension is shown to significantly enhance the performance of the operator with degraded images.

Recently, we have developed a nonparametric approach to texture analysis based on simple spatial operators like local binary patterns and signed gray level differences. Very good performance has been obtained in various texture classification and segmentation problems. This paper overviews our approach and presents examples to demonstrate its efficiency. Our results suggest that complementary f...

When there are many people who don't need to expect something more than the benefits to take, we will suggest you to have willing to reach all benefits. Be sure and surely do to take this computer vision using local binary patterns that gives the best reasons to read. When you really need to get the reason why, this computer vision using local binary patterns book will probably make you feel cu...

the globalisation of the commercial world, and the use of distributed working practices (Offshore/ onshore/ nearshore) has increased dramatically with the improvement of information and communication technologies. Many organisations, especially those that operate within knowledge intensive industries, have turned to distributed work arrangements to facilitate information exchange and provide co...

BACKGROUND Inadequate availability of healthy foods may be a barrier to achieving recommended diets. OBJECTIVE The objective was to study the association between the directly measured availability of healthy foods and diet quality. DESIGN We conducted a cross-sectional study of 759 participants from the Baltimore site of the Multi-Ethnic Study of Atherosclerosis. Diet was characterized by u...

BACKGROUND Diet is an important factor in the prevention of chronic diseases. Analysis of secular trends of dietary patterns can be biased by energy under-reporting. Therefore, the objective of the present study was to analyse the impact of energy under-reporting on dietary patterns and secular trends in dietary patterns defined by cluster analysis. DESIGN AND METHODS Two cross-sectional popu...
