Detailed Description

template<typename F>
class gtsam::TransferFactor< F >

Binary factor in the context of Structure from Motion (SfM). It is used to transfer transfer corresponding points from two views to a third based on two fundamental matrices. The factor computes the error between the transferred points pa and pb, and the actual point pc in the target view. Jacobians are done using numerical differentiation.
