Pouring cereal
Challenge:
|
Translation (TR), Rotation (RO), Speed (SP), Illumination (IL), fast shaking
|
Trackers:
|
bmic
tracker gets lost in fast speed (both light conditions); in diffuse
light with very fast movement bmic and esm get lost; in normal light
during very fast speed all three trackers get
lost; during increasing speed bmic gets lost in diffuse and normal light

Book III (insertion in magazine file)
Challenge:
|
Translation (TR), Occlusion (OC), Speed (SP), Illumination (IL)
|
Trackers:
|
during
all speeds and light conditions trackers get lost as occlusion occures;
in
very fast movement bmic gets lost before occlusion happens

Mug II (tilting)
Challenge:
|
Translation (TR), Perspective (PR), Texture (TX), Speed (SP), Illumination (IL), Specular Reflection (SR)
|
Trackers:
|
in very fast speed
trackers get lost through abrupt object motion
before tilting; in medium speed and normal light nnbmic and bmic when
tilted; in fast and very fast object motion in both light conditions
tracking fails as well as in increasing speed during or before tilting;
note different tilting hights and following different strong distortion

|
Trackers:
|
tracking
does not fail in diffuse light; nnbmic and bmic fail during very slow
as well as very fast speed; nnbmic fails in slow speed; note
differences in how much mug is rotated
