Architecture and Analysis of Color Structure Descriptor for Real-Time Video Indexing and Retrieval
نویسندگان
چکیده
Color structure descriptor (CSD) provides satisfactory image indexing and retrieval results among other color-based descriptors in MPEG-7. The superiority comes from the consideration of space distribution of pixel colors. In this paper, we proposed the first CSD hardware architecture which can generate CSD description with frame size 256 × 256 and 30 frames per second (fps). This architecture provides about 12 times speed-up than running on a 2.54 GHz microprocessor platform to achieve real-time applications like assisting rate control in video coding system and circumstance change detection in surveillance system.

متن کاملCompact color descriptor for fast image and video segment retrieval
Histograms are the most prevalently used representation for the color content of images and video. An elaborate representation of the histograms requires specifying the color centers of the histogram bins and the count of the number of image pixels with that color. Such an elaborate representation, though expressive, may not be necessary for some tasks in image search, filtering and retrieval. ...
متن کاملGrouping and Indexing Color Features for Efficient Image Retrieval
Content-based image retrieval (CBIR) aims at searching image databases for specific images that are similar to a given query image based on matching of features derived from the image content. This paper focuses on a low-dimensional color based indexing technique for achieving efficient and effective retrieval performance. In our approach, the color features are extracted using the mean shift a...
متن کاملAn efficient color representation for image retrieval
A compact color descriptor and an efficient indexing method for this descriptor are presented. The target application is similarity retrieval in large image databases using color. Colors in a given region are clustered into a small number of representative colors. The feature descriptor consists of the representative colors and their percentages in the region. A similarity measure similar to th...
