Effective Volumetric Feature Modeling and Coarse Correspondence via Improved 3DSIFT and Spectral Matching

Figure 2

An simple example demonstrating the effectiveness of ISM. (a) shows an initial correspondence set . (b) is the affinity matrix computed from . (c) shows the assignment graph which is unconnected. (d) shows the result of SM. (e) and (f) show the result of two revised steps of ISM, respectively.

(a) L

(b) M

(c) G

(d) SM

(e) ISM-step-1

(f) ISM-step-2
