#2703
Related to #2691:
The region motion detector relates to the pixel based bounds definition of the VideoSourceconfiguration. I couldn't find any definition regarding the origin of the Y axis.
The following sentences from spec and wsdl indirectly tell that the origin is in the lower left corner. However during plugfest we observed different vendor implementations.
All coordinate systems (e.g. Privacy Masks in the Media2 Service and Motion Regions in the Analytics service) that apply to a video source configuration are based on the resulting image after applying the Bounds and then Rotate to the source image.
and
Rectangle specifying the Video capturing area. The capturing area shall not be larger than the whole Video source area.
Proposal
Add to 5.2.2 Video source configuration
The origin of the bounds is located in the upper left corner of the video source.
