In this paper, we propose an interactive indexing scheme to facilitate an efficient search of Chinese calligraphic manuscript images based on hybrid features such as contour points and number of strokes. Different from conventional character retrieval and indexing methods , our proposed indexing algorithm allows user to choose other feature such as stroke of character they prefer to as query element. To better facilitate an efficient and unified retrieval, we then propose a
(HF-Tree)-based high- dimensional indexing scheme. Comprehensive experiments are conducted to testify its effectiveness and efficiency.
