C++ real_1d_array::getcontent方法代码示例

/*
 *
 * The cost function considered here is the following (with u(x,y,z),v(x,y,z),w(x,y,z) the flow at each pixel or super-pixel)
 *
 * E(u,v,w)=\sum_{s\inS}\sum_{n\in s} Huber(r(u_s,v_s,w_s),deltaHdataTerm) + \lambda \sum_{s \in S}\sum_{a\in Neigh(s) s.t. a<s} \left[ Huber(u_s-u_a,deltaHsmoothTerm) + Huber(v_s-v_a,deltaHsmoothTerm) + Huber(w_s-w_a,deltaHsmoothTerm) \right]
 *
 * S is the set of superpixels (stores in the partition). Thus, we impose that the flow is the same for voxels belonging to teh same supervoxel
 *
 * r(u,v,w)=I(x+u,y+v,z+w,t+1)-I(x,y,z,t)=imTarget(p+uvw)-imSource(p)
 *
 * I(x+u,y+v,z+w,t+1) and its partial derivatives need to be calculated using interpolation. As usual it is a trade-off between accuracy and speed.
