Capture.U Desktop enables you to view and, if required, to edit or delete regions of interest that were generated during data captured to sensor, prior to data export.

You can also create new regions of interest in Capture.U Desktop.

View and edit regions of interest

  1. Ensure your sensors are connected to Capture.U Desktop (see Connect sensors to Capture.U Desktop), and that you've selected the relevant trial and clicked Edit & download (see Download a trial from the sensors).

  2. On the Preview tab, any regions of interest that were defined during capture are displayed, both within the graph and on the Regions of interest tab at the bottom left.



  3. To edit a region of interest, either click its name on the Regions of interest tab or click the relevant Edit (pencil) icon .



  4. In the Edit region of interest dialog box, you can change the Start time and End time. To do this, either:
    • Enter new times in the Start time and End time boxes
      or
    • On the graph, drag the start and end time.



    Note that if necessary, the regions can overlap.
  5. When you're happy with your changes, click Save.

Delete regions of interest

You can delete regions of interest that were created during capture and any created later, with Capture.U Desktop.

To delete regions of interest:

  • On the Regions of interest tab, go to the relevant line and click the trash icon.

    As soon as you click the trash icon, the region of interest is immediately deleted with no further warning.
    You can recover deleted regions of interest only if they were created during data capture. To do this, exit Capture.U Desktop and restart.

Create regions of interest

You can create regions of interest in Capture.U Desktop, whether or not you created any during the original capture to sensor. If necessary, the regions you create can overlap existing regions.

  1. On the Regions of interest tab, click +ADD.



  2. In the Add region of interest dialog box, enter a name for the region of interest and specify a start and end time.
    To do this, either:
    • Enter new times in the Start time and End time boxes
      or
    • On the graph, drag to select the region.



  3. When you've finished adding the new region of interest, click Save.
    The newly created region of interest is displayed on the graph and as a new line on the Regions of interest tab.

Export regions of interest

You can export regions of interest either by using the Edit & download option, or by ensuring the settings are as required on the Settings tab and then using the one-click Download option.

To export regions of interest via Edit & download:

  1. Ensure your sensors are connected to Capture.U Desktop (see Connect sensors to Capture.U Desktop), and that you've selected the relevant trial and clicked Edit & download (see Download a trial from the sensors).



  2. On the Preview tab, go to the Export settings. 

  3. In the Export settings, choose either Full trial or By regions, or both.



    Select the relevant options to export the required output from your trial:

    • Full Trial (exports all the trial data, including any regions of interest, although if the trial is cropped, only data from the non-cropped region is exported)

      • Raw data Exports the full trial raw data (may be a cropped trial)

      • Aligned data Exports the full trial raw data (may be a cropped trial) aligned to the specified output rate (Hz)

      • X1D Exports the full trial raw aligned data (may be a cropped trial) at the specified output rate (Hz). Note that no region of interest information will be displayed in Vicon Nexus.

      • _notes.txt Provides trial information (data capture timestamp, exported cropped trial information, timestamps for each region of interest)

    • By Regions (exports the trial data from any regions of interest only)

      • Raw data Exports the raw data from regions of interest only

      • Aligned data Exports the aligned raw data from regions of interest only

      • _notes.txt Provides trial information (data capture timestamp, exported cropped trial information, timestamps for each region of interest)

  4. When you have finished specifying the required export and output settings, click Download.

To export regions of interest via one-click Download:

If you're using the Download option to export regions of interest (see Download with a single click), before you click Download, make sure the required options are selected in the Settings.

For details of what can be exported, see the previous Step 3.
