Multispectral imaging of wok fried vegetables

چکیده
This paper shows how multispectral images can be used to assess color change over time in wok fried vegetables. We present results where feature selection was performed with sparse methods from the multispectral images to detect the color changes of wok fried carrots and celeriac stored at +5°C over 14 days. A pairwise t-test was used to detect if the differences over days were significant. For both the original as well as a follow experiment significant differences were seen in particular for celeriac, but also to some extend for carrots.

Statistical Quality Assessment of Pre-fried Carrots Using Multispectral Imaging
Multispectral imaging is increasingly being used for quality assessment of food items due to its non-invasive benefits. In this paper, we investigate the use of multispectral images of pre-fried carrots, to detect changes over a period of 14 days. The idea is to distinguish changes in quality from spectral images of visible and NIR bands. High dimensional feature vectors were formed from all po...

متن کاملFruits and stir-fried vegetables increase plasma carotenoids in young adults.
We examined the plasma levels of carotenoids in young adults after a dietary intervention composed of increased intakes of fruits and stir-fried vegetables from a Taiwanese mixed diet. Thirty-four apparently healthy, non-smoking subjects who normally ingested less than two and a half servings of fruits and vegetables daily were selected for the study. Meals changed were lunch and dinner on week...
متن کاملSpectral Estimation of Printed Colors Using a Scanner, Conventional Color Filters and applying backpropagation Neural Network
Reconstruction the spectral data of color samples using conventional color devices such as a digital camera or scanner is always of interest. Nowadays, multispectral imaging has introduced a feasible method to estimate the spectral reflectance of the images utilizing more than three-channel imaging. The goal of this study is to spectrally characterize a color scanner using a set of conventional...
