Contactless monitoring of heart and respiratory rate in anesthetized pigs using infrared thermography
Fig 3
Correlation plot and Bland-Altman plot comparing HR assessed with infrared thermography (HRIRT) and HR assessed using ECG (HRGS).
The plots include the data from all the 17 animals. A: The plot on the left shows an R-squared of 0.9598 and a sum of squared errors of 4.8 bpm. B: The graph on the right presents a bias of -0.14 bpm (solid line), and the 95% limits of agreement vary between -9.3 and 9.0 bpm (dashed lines).
