Mostly AR and Stuff

No camera – no fun

As everyone twittering about new Vuzix Wrap 920AV glasses it’s not clear for me from the photo
new glasses
if they have camera or not.
Old Vuzix SightMate have clearly visible camera.

I don’t see anything like that on the new glasses. Vuzix promise “augmented reality features”, but no camera – no AR. What would be point of stylish videoglasses with ad-hock attached camera ?

PS. A new announcement from Vuzix saying that glasses will have attachable stereo camera add-on. We well see how good will it looks.

SURF scale scpace

I continue to test SURF, in respect to scale space. Scale space is essentially a pyramid of progressively more blurred or lower resolution images. The idea of scale invariant feature detection is that the “real” feature should be present at several scales – that is should be clearly detectable at several image resolution/blur levels. The interesting thing I see is, that for SURF, at least for test images from Mikolajczyk ‘s dataset, scale space seems doesn’t affect detection rate with viewpoint change. I meant that there is no difference if feature distinct in several scales or only in one. That’s actually reasonable – scale space obviously benefit detection in the blurred images, or noisy images, or repeatability/correspondence in scaled images , and “viewpoint” images form Mikolajczyk ‘s dataset are clear, high resolution and about the same scale. Nevertheless there is some possibility for optimization here.
