Figure 2: Successful identification of areas with invalid strain calculations by bad region analysis.
(A) The quantity of bad regions in the digitally transformed images analyzed using the cumulative method increased consistently after 6% applied strain, while the incremental quantity remained at 1%. (B) The quantity of bad regions for all the tendon samples increased steadily at larger strain increments. Experiment 2 was considered an outlier and, thus, is not included in the mean and standard deviation bars.
