Grassfire method for spot matching is proposed based on similarity comparison of topological patterns for neighbor spots. Grassfire method is an algorithm where spot matching is performed as if fire spreads all around on grass. Spot matching starts from a seed spot pair confirmed as a matched pair of spots and spot matching spreads to the direction where the best matching result is produced. In this paper, the simple type of grassfire method where a seed spot pair is manually selected and spot matching is conducted under the circumstances without outlier spots is studied to examine the potential of grassfire method. The proposed method outperforms matching methods by random combination of spots in terms of speed and accuracy.
