We define an easy and hard split.

The analysis and use of egocentric videos for robotic tasks is made challenging by occlusion due to the hand and the visual mismatch between the human hand and a robot end-effector. In this sense, the human hand presents a nuisance. However, often hands also provide a valuable signal, e.g. the hand pose may suggest what kind of object is being held.

Latter approach was a breakthrough in 1990s, it lead to interior-point methods.

Bi-narization, an ultra-compression algorithm, offers the potential for effectively accelerating DMs.
