8 Conformance Testing
Table 2 provides the Conformance Testing Method for OSD-VDI AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present and conform with the Qualifier, if present.
Table 2 – Conformance Testing Method for OSD-VDI AIM
| Receives | Visual Scene Geometry | Shall validate against Visual Scene Geometry schema |
| Body Descriptors | Shall validate against Body Descriptors XML schema | |
| Produces | Point of View | Shall validate against Point of View schema |
9 Performance Assessment
Performance Assessment of an OSD-VDI AIM Implementation shall be performed using a dataset of static 3D Visual Scenes each containing an Entity described by Body Descriptors and Visual Scene Geometry annotated with the ID of the Visual Object in the Visual Scene the index finger of the Entity is pointing to.
The Performance Assessment Report of a OSD-VDI AIM Implementation shall include:
- The identifier of the dataset.
- The Accuracy of Object identification.
