DEN calculation is extremly slow!

[xulman]

C3DH-H157/01, 54 frames... took cca 11 hours! Check the code -- wasn't that bad previously (ScoreAnnotatedVideos src code).

Would it be possible to calculate it in one shot, i.e. for all objects at the same time? The DT-like iterations would be progressing only on empty background plus updating only own data. There would have to be extra map-image to tell whom the DT non-zero values belong to. If we run into values of somebody else, the distance is likely to be the sum of mine and his values (but wait for round to finish to see everything updated).

this is connected to issue #2

there is a AABB calculator with bounded-view on the orig image... could help to narrow down the search region (instead of searching through the whole image), thus accelerating?
