The document discusses a novel attribute-assisted reranking model for web image search that utilizes semantic attributes for refining text-based image search results. It proposes a hypergraph learning approach that incorporates both low-level visual features and attribute features, aiming to improve the accuracy of image retrieval by simultaneously considering multiple information sources. Experimental results show the effectiveness of this method in addressing the limitations of existing text-based retrieval systems.

Most existing reranking approaches are based on low-level visual features. In this paper, we propose to exploit semantic attributes for image search reranking. Based on the classifiers for all the predefined attributes, each image is represented by an attribute feature consisting of the responses from these classifiers. A hypergraph is then used to model the relationship between images by integrating low-level visual features and attribute features. Hypergraph ranking is then performed to order the images. Its basic principle is that visually similar images should have similar ranking scores. In this paper, we propose a visual-attribute joint hypergraph learning approach to simultaneously explore two information sources. A hypergraph is constructed to model the relationship of all images. We conduct experiments on more than 1,000 queries in MSRA-MMV2.0 data set. The experimental results demonstrate the effectiveness of our approach.

However, text-based image retrieval suffers from essential difficulties that are caused mainly by the incapability of the associated text to appropriately describe the image content. The existing visual reranking methods can be typically categorized into three categories as the clustering based, classification based and graph based methods. The clustering based reranking methods stem from the key observation that a wealth of visual characteristics can be shared by relevant images. In the classification based methods, visual reranking is formulated as binary classification problem aiming to identify whether each search result is relevant or not. Graph based methods have been proposed recently and received increasing attention as demonstrated to be effective. The multimedia entities in top ranks and their visual relationship can be represented as a collection of nodes and edges DISADVANTAGES OF EXISTING SYSTEM: In the classification based methods, visual reranking is formulated as binary classification problem aiming to identify whether each search result is relevant or not. The framework casts the reranking problem as random walk on an affinity graph and reorders images according to the visual similarities. PROPOSED SYSTEM: We propose a new attribute-assisted reranking method based on hypergraph learning. We first train several classifiers for all the pre-defined attributes and each image is represented by attribute feature consisting of the responses from these classifiers.

This paper serves as a first attempt to include the attributes in reranking framework. We observe that semantic attributes are expected to narrow down the semantic gap between low-level visual features and high level semantic meanings. ADVANTAGES OF PROPOSED SYSTEM: We propose a novel attribute-assisted retrieval model for reranking images. Based on the classifiers for all the predefined attributes. We perform hypergraph ranking to re-order the images, which is also constructed to model the relationship of all images. Our proposed iterative regularization framework could further explore the semantic similarity between images by aggregating their local Compared with the previous method, a hypergraph is reconstructed to model the relationship of all the images, in which each vertex denotes an image and a hyperedge represents an attribute and a hyperedge connects to multiple vertices.
