Abstract Objective . In previous studies, the factors affecting accuracy of imaging photoplethysmography (iPPG) heart rate (HR) measurement have been focused on light intensity, facial reflection angle, and motion artifacts. However, factor specularly reflected has not studied in detail. We explored effect HR estimation proposed an method for direction radiated light. Approach To study influenced by light, we control component controlling its angle. A total 100 videos from four different...
Region-of-interest (ROI) selection is a key process for the remote heart rate (HR) measurement approach. Previous studies have shown that selected ROI could easily be lost under head-rotation circumstances and does not perform well drastic changes in illumination. To solve problems, this work proposed novel adaptive method. First, we collected dataset modeling signal-to-noise ratio (SNR) evaluated by illumination reflection angle. Second, established an SNR-estimated model studying...
With the advance of technology threshing and re-drying, formula mode guided by quality homogeneity tobacco leaves will become mainstream. A high-quality re-drying module can achieve stability intrinsic physical leaves, make full use improve value purchased processing enterprises, give play to characteristics raw material modules. The most important requirement is stable quality, fluctuation internal chemical composition controlled at a low level, that is, homogenization key affecting...
