Shape Based Image Retrieval Using Rough Sketch
Details
We propose a new feature for content-based image retrieval using sketch. The proposed feature is based on the shape of object's edge. The feature extraction method uses the relative positional relationship between pixels on binary lines image as histogram. Hence this feature has advantage of rotation-invariant, shift-invariant and scale-invariant. Applying the proposed feature to image retrieval, it is possible for users to retrieve objective images by rough sketch drawn with input devices(mouse, electronic pen, etc.). To verify the effectiveness of this method, we tested the method on two separate databases. Experimental results show that the proposed method is effective.
