A Mean-Shift-Based Feature Descriptor for Wide Baseline Stereo Matching

Figure 6

(a) Dotted lines with arrow denote the paths which are coming from the feature points to the center of the fan area. And the center is decided by those SIFT feature points’ positions in the fan area. (b) The differences (image gradient feature is used to present each point’s characteristics) between real feature and linear interpolation of each point.
