CEDD: Color and Edge Directivity Descriptor: A Compact Descriptor for Image Indexing and Retrieval
(Springer-Verlag, 2008)This paper deals with a new low level feature that is extracted from the images and can be used for indexing and retrieval. This feature is called “Color and Edge Directivity Descriptor” and incorporates color and texture ...
-
FCTH: Fuzzy color and texture histogram. A low level feature for accurate image retrieval
(IEEE (Institute of Electrical and Electronics Engineers , United States), 2008)This paper deals with the extraction of a new low level feature that combines, in one histogram, color and texture information. This feature is named FCTH - Fuzzy Color and Texture Histogram - and results from the combination ...
-
Hybrid scheme for fast and accurate image retrieval based on color descriptors
(ACTA Press, Canada, 2007)This paper proposes a new image retrieval system, thatuses only color features and it's based on a hybrid scheme which combines crisp and fuzzy techniques, in order to retrieve color based similar images. The system ...
