That's surprising actually :D. Could you tell me what commands you used locally, when you tested my branch? Also does the overlayImage show up in /usr/share/digikam/data?

You've done great job so far! In addition, I have some questions (Q) and comment (C).</div><div><br></div><div>For displaying person thumbnails as icon for each person tag:</div><div><b>Q: </b>If a user has already some faces recognized (tagged) in a tag but the tag does not have the icon yet. When the first time they use this new feature, will the icon be selected randomly among those faces tagged already? Or do they have to wait until they tag a new face for that tag?</div></div></blockquote><div> Yes, this is an issue. The current implementation only adds Icon, when the User performs some action related to the Face Tag. I actually started a discussion on this a week back : <a href="http://digikam.1695700.n4.nabble.com/Update-FaceTags-List-to-assign-Tag-Icons-to-all-tt4712891.html">http://digikam.1695700.n4.nabble.com/Update-FaceTags-List-to-assign-Tag-Icons-to-all-tt4712891.html</a><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><b>C: </b>For me, when I firstly tag a face to a tag, that face becomes the icon for that tag. However, if I delete that face in the tags (and it's not the last face remaining in the tag), that face is still the icon for that tag. In my opinion, user can make mistake and wrongly select a face for a tag, so when that face is deleted from the tag, the icon has to be chosen randomly among other faces already tagged that remain in the tag.</div><div><br></div></div></blockquote><div>Sure, this looks implementable. I'll try this out. <br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div></div><div>For Helpbox:</div><div><b>C: <br></b></div><div><ul><li>I think that you should not use your photo for helpbox. As Gilles said, you should not use faces of popular people, since there may be issues later. In my opinion, just put a face placeholder (like when you haven't set your avatar yet on Facebook for example), and put a name on it. User will understand anyway.</li></ul></div></div></blockquote><div>This is a great idea, I hadn't thought of it. I'll do this. <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><ul><li>In Face Recognition tab, for your last sentence, Sensitivity/Specificity is not accuracy over speed actually. It works in a way that if you go towards Specificity (slide to the right), you ask the engine to recognize faces only when they are very close to tagged faces -> this leads to higher accuracy, but less faces recognized (since you require a high standard). If you go towards Sensitivity (slide to the left), you decrease the standard so more faces can be recognized but less accuracy.<br></li></ul></div></div></blockquote><div>Oh Alright. I actually wrote that because of a line in the Online Handbook : "In Parameters you can try to find a balance between speed and accuracy that suits your needs.". The handbook is for an older version of digiKam however, so it might be different from current status. Anyway, I will fix the sentence.</div><div><br></div><div>Kartik <br></div></div></div>
