Writer Identification Using GMM Supervectors and Exemplar-SVMs

作者:

Highlights:

• We provide a robust method for offline writer identification.

• We integrate Exemplar-SVMs, which greatly improve the recognition rate.

• We show that RootSIFT descriptors sampled at the contour are strong features.

• We investigate different encoding strategies next to GMM supervectors.

• We evaluate our method on three publicly available datasets (ICDAR13, CVL, KHATT).
