Interest in using herbal medicines to treat the hypercholesterolemia is increasing. Cranberry extract could decrease plasma cholesterol, however, the active ingredients and the underlying mechanisms remain largely unknown.The present study was to test the hypothesis that cranberry anthocyanins (CrA) were at least one of the active ingredients responsible for the cholesterol-lowering activity of cranberry...
A novel method to estimate the 3D location of a circular feature from a 2D image is presented and applied to the problem of objective dietary assessment from images taken by a wearable device. Instead of using a common reference (e.g., a checkerboard card), we use a food container (e.g., a circular plate) as a necessary reference before the volumetric measurement. In this paper, we establish a mathematical...
In dietary studies, an accurate tool for diet assessment is highly required. In this paper, we present a new approach to the estimation of the food volume from a single input image based on the virtual reality (VR) technology. A virtual reality model is built for the estimation process and an algorithm is developed for the calculation of food volume. Experimental results have indicated high accuracy...
