    <p>There is no GUI of OpenCV able to do what you want. You will be able to <strong>use</strong> OpenCV for some aspects of your problem, but there is no ready-made solution waiting there for you.</p> <p>While it's definitely possible to solve your problem, the learning curve for this problem is quite long. If you're a professional, then an alternative to learning about it yourself would be to hire an expert to do it for you. It would cost money, but save you time.</p> <p><strong>EDIT</strong></p> <p>As far as template matching goes, you wouldn't normally use it to solve such a problem because the thing you're looking for is changing appearance and shape. There aren't really any "dynamic parameters to set". The closest thing you could try is have a <strong>massive</strong> template collection that would try to cover the expected forms that your target may take. But it would hardly be an elegant solution. Plus it wouldn't scale.</p> <p>Next, to your point about face recognition. This is kind of related, but most facial recognition applications deal with a controlled environment: lighting, distance, pose, angle, etc. Outside of that controlled environment face detection effectiveness drops significantly. If you're detecting objects in a movie, then your environment isn't really controlled.</p> <p>You may want to first try a simpler problem of accurately detecting <strong>where</strong> the characters are, without determining <strong>who</strong> they are (video surveillance, essentially). While it may sound simple, you'll find that it's actually non-trivial for arbitrary scenes. The result of solving <strong>that</strong> problem may be useful in identifying the characters.</p>

    1. COMy lack of knowledge caused me to believe that a simple call to testTemplate(source, template, ...) with some dynamic parameters would do the trick. It seems like there is much more involved though. However, I also figured that what I want is nearly the same as Face Recognition, isn't it? There surely must be more out there regarding this type of object recognition?

    2. COI've tried to answer your questions in an edit. I'm in a bit of a rush now, so if I've missed something let me know and I'll come back to it.

    3. COThanks. It is not quite the answer I was hoping for though ;) Assuming that there really is nothing out there on the web (my searches would comply with this assumption) that describes a compareable situation as mine, I guess I would have to start from scratch and really dig into this field of Computer Vision. It seems like a highly sophisticated and rather complex task, so I might just have to get my mind off this "little plan".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
