Image Re-ranking Based on Extraction of Semantic Regions
|
Abstract:
It is difficult for current image search engines to accurately grasp the real intention of users. Based on the search results, we propose three clustering algorithms to extract semantic regions of Web images. These methods include K-means clustering with determined k centers, expectation maximization clustering with the determined parameters, and semi-supervised K-means clustering. We then select the salient regions with the high salient scores as the semantic regions. We demonstrate the experimental results by comparing the three clustering algorithms. The proposed image re-ranking system can more accurately show the ordered search results than web image engines.
