Fig. 3From: Anisotropic non-rigid Iterative Closest Point Algorithm for respiratory motion abdominal surface matchingCorrespondence maps for isotropic (left) and it’s modification with enhanced landmark weighting (right) ICP. The axes present the size of the registered target point cloud. The number of correspondence for every point of target point cloud is presented in color value. The preferred value is green (one correspondence). The black value means that the point attract no correspondence, other values indicate more correspondenceBack to article page
