Graph based approaches succeed in producing meaningful regions in images when they are to be stored as entities in a database for content-based retrieval. Despite controlling various parameters, the bottom-up approach produces too many segments for an Internet search retrieval scheme. The top-down scheme can be adjusted for wide area searches, but has a high computational cost. In this work we combine the two approaches and retain the advantages of both approaches. The key idea is to use local approach for reducing the size of the problem that is fed to the normalized cut approach. Our algorithm runs in O(n log n) time.
