Hi Silvia,

Thank you very much for your comments.

Scenario 1.2[1] is a scenario in "Linking to and Display of Media
Fragments" use case.
[1] http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/#scenario1.2

Yes, as you pointed out, the media fragments URIs are used for
specifying some regions of images in my use cases.

But the purpose is different. In my use cases, the media fragments URIs
are used not for "linking and displaying them" but for "exchanging
fragments data among various analysis engines in server-side".

Considering above aspect, I think some new requirements for media
fragments URIs might be raised up. For example, how to embed the
accuracy of cropping in media fragments URIs, a negotiation protocols
for aligning accuracy of media fragments, exchanging combination of
several fragments in different images, etc.

I am not sure if my use cases should be integrated in "Regions of an
Image" scenario because they are same in using media fragments as
specifying regions of images, or we had better to treat them as
different use cases because we use media fragments for analysis engine
collaboration in server-side and raise up some further new requirements
for media fragments.

Let me hear your opinion.

(My apologies if I didn't followed your previous discussions enough...)

With my best regards,

| Hi Nobuhisa,
| In my opinion, all your use cases are just examples of scenario 2
| http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/#scenario1.2
| in the Linking and Display use case of the Requirements document.
| Face recognition identifies a square region in an image that is linked
| to, so does trajectory analysis (if you use a origin and a target
| position) and so does clothes recognition.
| The "Region of an Image" use case should be sufficient to cover your
| uses. Your uses are awesome, btw, but they just don't require any
| extra use cases in the requirements document.
| Regards,
| Silvia.
