MPEG-7 Feature Visualization for CBIR Systems

Content-Based Image Retrieval techniques are developed in an attempt to make fast and efficient exploration of visual content possible. In addition, standard MPEG-7 visual features should offer interoperability across different multimedia database systems. This paper presents an attempt to bridge the gap between the target semantic concepts of multimedia data and the available low-level visual descriptors by providing an intermediate feedback to the user of a CBIR system where the features selected in his query are visualized according to his input image. Two MPEG-7 visual features, a color feature (Color Layout Descriptor CLD) and a texture feature (Edge Histogram Descriptor -EHD), were chosen for this purpose.
