Summary
[edit]| Description |
English: Supplementary Movie 11 Image Analysis: Image analysis was used to measure microwheel rolling velocity, camber angle and rotation frequency. The left window shows the original experimental video and the right the image-processed version. To calculate rolling velocity, the microwheel center (red dot) was recorded. To determine the camber angle, the white pixel count inside the big (embracing) square during translation was used. Rotation frequency was determined from pixel sum fluctuations inside the small square (on the bottom right quarter of the microwheel). |
