…ntained in a rectangular RoI. Missing cases where the circle is bigger than the RoI and where the circle is near a corner and thus crosses two borders
…ses where a single axis is crossed). WiP for two perpendicular axes crossing
…e of the two axes outside the RoI
…obability scheme, which is the ratio of the number of visible pixels divided by the theoretical number of visible pixels
…ons on each axis for the left case
…ch axis + top / bottom only
… top and bottom are crossed in the RoI
… left (or right) axis is crossed
…nd bottom are crossed and the third axis is touched
…top + the lateral axes are crossed once and the bottom one is not crossed in the RoI
… where the circle intersects the only the bottom and lateral side, once each
