In this paper, we present an approach for image reconstruction from local phase vectors in the monogenic scale space. The local phase vector contains not only the local phase but also the local orientation of the original signal, which enables the simultaneous estimation of the structural and geometric information. Consequently, the local phase vector preserves a lot of important information of...

conclusion: this study showed positive effect of the 2000 iu/day oral vitamin d on the serum level elevation of this vitamin in reproductive women. results: at baseline the mean serum levels of vitamin d in the control group was 23.34 ± 15.87 nmol/l and in intervention group was 25.13 ± 18.46 nmol/l, that these values didn’t have any significant difference (p = 0.43), while after intervention, ...

abstractthe occurrence of deoxynivalenol (don) in retail foods in tehran (iran) was determined using high-performance liquid chromatography technique and immunoaffinity column as the clean-up step. a method was validated for analysis of don in rice, bread, puffed corn snack and wheat flour. the average recoveries and precision (rsd) for don in different foods ranged 84.2-93.1% and 2.9-12.0%, re...

a diverse range of foods has been shown to increase energy and micronutrients intake in the developing countries. it is widely asserted in the literature and development circles that farm household access to irrigation dam can provide a significant improvement of household’s dietary diversity. this study set out to assess the role of kampe irrigation dam on farm household dietary diversity in k...

rapid changes in lifestyle and industrialization of communities have an important effect on food intake pattern of society. regarding the lack of enough data about dietary habits and nutrient intake of adolescents in our society, this study was performed in a group of adolescent girls in lahijan, north of iran. in this cross-sectional study, 400 high school girls aged 14-17 years selected by ra...

We consider reconstruction algorithms using points tracked over a sequence of (at least three) images, to estimate the positions of the cameras (motion parameters), the 3D coordinates (structure parameters), and the calibration matrix of the cameras (calibration parameters). Many algorithms have been reported in literature, and there is a need to know how well they may perform. We show how the ...

Abstract 3D reconstruction is one of the main components in computer vision. The dynamic stereo model applied to rotating objects on a turntable provides a way of analyzing object’s surface or 3D position. In this paper, we extend work reported in [5]: we correct an error in computing the rotational angle; and we present a new procedure for 3D object reconstruction with unknown rotation angle b...
