Spatial averaged edge position calculated at different time steps, depicts the wound closing rate at a 1.5 Pa and b 10 Pa. Using conservative Canny method (orange), as well as iCD (dark blue), iDSD (blue) and freehand (green) c Relative errors plotted as boxplot diagram compiled from a and b. The median is plotted as a vertical line in the box The upper box bound corresponds to the median of the upper half of the data and so also for the lower part. The mean is shown as a cross. The length of the whisker corresponds to 1.5 times the distance between the lower and upper box boundary; outside this range, the data are marked as outliers (circle)
