External Fixture |
Specifies a reference to a Fixture or Fixtures data structure. This fixture data will be passed into the ViDi tools, and will be used to define the views for each image. When using an external fixture, within the ViDi tool's Region of Interest (ROI), you will need to select External. Then, from the Image Database menu, select Update All Training Fixtures, and then modify the ViDi tool's ROI. You can also update the ViDi tool's reference to the external fixture data by selecting the ViDi data structure, right-click and select Update Training Fixtures. |

ViDi Outputs
Returns |
A ViDi data structure containing the neural network model of the ViDi tool or tools. |
Results |
When a ViDi function is inserted into the spreadsheet, a results table can be created, based on the ViDi Results Vision Data Access Functions by right-clicking on the ViDi data structure and selecting Insert Getters. |
