Parallel contact (P), Anti-parallel contact (A) and No-contact (N) are the three classes considered by the coarse contact and orientation predictor. Inline graphic is the percentage of correctly predicted pairs in equation (7), PPVInline graphic is the Positive Predictive Value on class X in equation (8) and TPRInline graphic is the True Positive Rate on class X in Equation (9).
