Figure 8From: Video image-based analysis of single human induced pluripotent stem cell derived cardiomyocyte beating dynamics using digital image correlation Assessment of the effect of noise on video beating analysis. Varying degrees of speckle noise variance were added to a video for testing noise resistance. A-D: Example images for four noise variance levels are shown: 0, 0.003, 0.005, and 0.015.Back to article page
