Synergy of foreground–background images for feature extraction: Offline signature verification using Fisher vector with fused KAZE features

作者:

Highlights:

• KAZE features from foreground and background signature images show good performance.

• Fused KAZE features with representation-level fusion further improve performance.

• FV provides a more precise spatial distribution of the characteristics per writer.

• PCA for the FV provides a more compact vector without significant performance loss.

• This method yields lower error rates than existing signature verification systems.
