Description hardy.public 2018-01-03 17:19:44 UTC

When I click the "Add a Face Tag" icon and the cross hairs hover over an existing face region boundary, the existing face region appears.

In other words, if the existing faces are close together, the existing face tags are distracting when trying to add the new face region with elegant proportions and position.


Expected (Wished For) Behaviour
===============================
When "Add a Face Tag" is in progress, disable appearance of existing face tags until the new face tag is completed.


If a user wants the existing tags to show while drawing a new tag, they have the option to press "Show Face Tags" first.

I do not really see a problem here. It is still possible to create a new face rectangle, even if it begins within an already existing one. Maybe create a screencast?

For example, in the attached images, I want to add a new face tag for the woman in the green jacket.

An existing tag, Test4, is displayed when I am placing the top right corner of the new tag. See StartDrawingFaceTag.

Furthermore Test4 persists as I leave its region and finish the opposing corner of the new tag. See EndDrawingFaceTag.

For me at least, Test4 is a distraction when all I want to do is focus on drawing the new face tag centred and proportioned to WomanInGreen.

Hence I would simply prefer it that existing face tags are suppressed when I have initiated drawing a new one after clicking the Add A Face Tag button. 

Unless of course there is an argument to display Test4 while I am drawing the new face tag but I cannot think of a reason why this would be useful.

Screencast

I attach a screencast of the wished for behaviour. It's not a problem but a matter of preference I suppose but I do not want to see the face regions of Test5 or Test6 after clicking "Add a Face Tag" until I have confirmed the new face region which happens to overlap. It's a distraction, no more than that.
