Grasp Point Detection

Methods

Histogram of polar coordinates

Implemented in #81.

see Ramisa at al..

Concavity

Another option is to use concavity,

Determining Where to Grasp Cloth Using Depth Information, Ramisa at al.

Ramisa at al. uses a three finger gripper, therefore, they seek hill like points. Their method use a histogram of a polar coordinates of points from some neighbourhood. The histogram is then measured by entropy. The disadvantage is that the valleys have also high response.

This approach was implemented in #81.
