Bread Water Content Measurement Based on Hyperspectral Imaging |
|
| Abstract | Water content is one of the most important properties of the bread for
tasting assesment or store monitoring. Traditional bread water content
measurement methods mostly are processed manually, which is destructive and
time consuming. This paper proposes an automated water content measurement
for bread quality based on near-infrared hyperspectral imaging against the
conventional manual loss-in-weight method. For this purpose, the hyperspectral
components unmixing technology is used for measuring the water content
quantitatively. And the definition on bread water content index is presented for
this measurement. The proposed measurement scheme is relatively inexpensive
to implement, easy to set up. The experimental results demonstrate the
effectiveness. |
