Multimedia Content Filtering, Browsing, and Matching Using MPEG-7 Compact Color Descriptors [chapter]

Santhana Krishnamachari, Akio Yamada, Mohamed Abdel-Mottaleb, Eiji Kasutani
2000 Lecture Notes in Computer Science  
Without such descriptions, the average consumer would be left helpless with enormous amount of data and no viable tool to efficiently access the content.  ...  Here we present two color descriptors that are very compact in size, namely, the compact color histogram descriptor and the compact color layout descriptor.  ...  The former is used to express color content of an image for similarity-based retrievals. Color histograms are often used for this purpose.  ...
