Initial Poses and Tracking Settings Manual

1. Complete capture of movements

2. Open Simi Shape

3. Select a trial for a new athlete in the 'Simi Motion project' box.

4. Choose the correct Track settings based on athlete pitch hand in D:/Settings folder.

5. Select the default initial pose for the proper exercise and side (left or right) if applicable, in D:/InitialPoses.

6. Click 'OK' to Open Shape

7. Using the lower slide bar, find the frame of video when the athlete matches closest to the loaded initial pose.

8. Go to [Edit > Scale Box] to be able to change the model's height.

9. Type the athlete's height in meters into the 'Set model scale to size [m]:' box and hit Enter on the keyboard to lock in that size. Then exit out of the Scale box window.

10. Click Image Processing or Segmentation (depending on shape version the button label may be different) on the left-hand side to open the segmentation box. Choose the drop-down menu and select 'Background subtraction'. Adjust the Angle, Upper, and Lower sliding bars to optimize the silhouette of the athlete. The goal is to eliminate background and maximize the picture of only the athlete.

11. Complete Step 10 above for each camera view by selecting the drop-down menu and choosing the next camera. You can also right-click on a camera view to open that view in the segmentation box. Once all camera views are optimized, exit out of the window.

12. Save the Settings by going to [Settings > Save settings…] and overwrite the existing settings file.

13. Click the Optimize Pose button many times until the model falls into the silhouette of the athlete. In case an extremity or segment will not automatically fit the silhouette, use the following hot keys to move the segment near the correct location and hit Optimize Pose many more times until the model adheres to the silhouette.

• Hold Alt, Right Click on a segment and hold the Right Click → Allows you to rotate the highlighted segment around its' axis.
• Hold Shift, Left Click and Hold on a segment → Allows you to move the highlighted segment in the transverse plane.
• Hold Shift, Middle Click (press in the scroll wheel) and Hold on a segment → Allows you to move the segment in the frontal plane.
• Hold Shift, Right Click and Hold on a segment → Allows to move the highlighted segment in the sagittal plane.

14. Once the model matches the athlete, save the model as an initial pose. Go to [File > Save as initial pose…]. Change the filename to match the format in your initial pose folder, 'Name_init.shpdata' and Click OK. Click NO on the following window.

15. Go to [Settings > Load settings], as previously we loaded track_R.shp settings, we will also want to optimize background segmentation for init_R.shp settings.

16. Complete steps 10-12 again for the init_R.shp settings and overwrite the settings file.

17. Exit out of Shape and Quit without saving by unchecking the boxes next to Save Simi Motion Project, Save Model Data and Save Settings.
