Producing fine resolution thematic map using interpolation then classification

摘要

In this paper, a framework based on fine resolution thematic map, namely, interpolation then classification (ITC) is proposed. Firstly interpolation algorithm is applied in the original coarse hyperspectral imagery to derive a high-resolution imagery with generous prior information. Then fine resolution thematic map is derived from the high-resolution imagery by the available classification methods. Experiments on two real hyperspectral imagery showed that the proposed method produced higher accuracy result than interpolation-based soft-then-hard super-resolution mapping (I-STHSRM).
