Abstract:

This paper presented a contour-based freehand sketch retrieval method, which used Fourier Shape Descriptor to unify the shape representation of the sketchy graphics in the sketchy graphics database and user input and retrieved the images by calculating the similarity between them. This method improves the computation efficiency and avoids the order-sensitivity of the strokes. The result of experiments shows that the proposed method has good retrieval performance and efficient user adaptation.

Key words: freehand sketch retrieval, fourier shape descriptor, user adaptation

摘要：
