According to the feature of the impurity, one image with twice processing is put forward based on blob analysis, which eliminates impurities that were brighter or darker than normal particles. With the image processing system developed by Matrox Imaging Library, black and white blobs are extracted for twice with one function, and then the size and the position of impurities are calculated quickly through mathematical morphologic and blob analysis. The method can be extended and applied in other fields due to its advantages of quick speed and high accuracy.展开更多

Methods: This study conducted secondary analyses of the National Health and Nutrition Examination Survey, 2005-2010. Cluster analysis was used and identified 8 grain patterns: 1) no consumption of main grain groups, 2) crackers and salty snacks, 3) yeast breads and rolls, 4) cakes, cookies, and pies, 5) cereals, 6) pasta, cooked cereals and rice, 7) quick breads, and 8) mixed grains. Results: Adults consuming “cereals”, “pasta, cooked cereals and rice”, and “mixed grains” had a better diet quality compared to no grains. Consuming many, but not all, of the grain food patterns resulted in less saturated fat and lower added sugars. Adults consuming “cereals”, “pasta, cooked cereals and rice” and “quick breads” had greater dietary fiber intake vs. no grains group. Calcium intake was increased in the cereals group, while magnesium intake was greater in adults consuming “cereals” and “pasta, cooked cereals and rice” vs. no grains. Vitamin D (D2 + D3) intake was higher in adults consuming “cereals”, “pasta, cooked cereals and rice”, and “mixed grains” vs. no grain group. Adults consuming “pasta, cooked cereals and rice” had lower body weights (79.1 ± 0.7 vs. 82.5 ± 1.2 kg;P = 0.009) and waist circumference (95.2 ± 0.6 vs. 98.2 ± 1.0 cm;P = 0.004) in comparison to those consuming no grains. Conclusions: Certain grain food patterns are associated with greater 2015-2020 Dietary Guidelines’ shortfall nutrients, better diet quality and lower body weights in adults. Additionally, certain grain food patterns are associated with lower intake of nutrients to limit, including saturated fat and added sugars.展开更多
