History
2009.09.14. Systematic search
On this video, we've tested the systematic search around scene, in order to guarantee system will explore all scene around it. Thus, we'll search faces using random search with systematic search. Now, we're sure that any face will be out of range.
2009.09.09. Following faces around scene, with saliency and liveliness dynamics
Here, we can see a visual attention mechanism. Now, our algorithm chooses the next fixation point in order to track several objects around the robot simultaneously. This behavior is based on two related measurements, liveliness and saliency. The attention is shared among detected faces and new exploration points, when forced time to explore scene is out. Moreover, this time is depends on how many faces are detected. If we've several detected faces, this time will be large...
2009.09.03. Following faces around scene
Now, as we told last time, we have a continuous space in order to gaze the pan-tilt unit according to the major saliency object. Sometimes, we'll have to introduce some virtual faces to explore new zones... And when we find a face, we stop there watching it. Next step is instead of stopping, following that face...
2009.08.31. Following multiple faces from different scene perspectives
Here, you're the last version of this "intelligent followface". We've decided to change our point of view and now instead of having three parts on the scene, we'll have a continuous space in order to gaze the pan-tilt unit according to the major saliency object. Sometimes, we'll have to introduce some virtual faces to explore new zones...
