Research on JPEG image retrieval based on color layout
GU Hong-fei, Zhang You-sheng · Journal of Hefei University of Technology · 2006
Image retrieval techniques are crucial for multimedia applications.In the paper,a fast image retrieval method based on the DCT domain and correlative feedback is presented,which aims at JPEG images and uses color layout descriptors in the MPEG-7 standard.As the method only needs entropy decoding,the speed of extracting image features is improved and storage space saved.The experiment result shows that the method has a high retrieval speed and a good effect.
