… This article demonstrates that color histograms of multicolored objects provide a robust,
efficient cue for indexing into a large database of models. It shows that color histograms are …

… Swain’s color indexing method to be illumination independent, not by preprocessing for
color constancy, but rather by indexing on an illumination-invariant set of color descriptors. …

… In this paper, we propose a new color feature for image indexing/retrieval called the color …
of pairs of colors, (ii) it describes the global distribution of local spatial correlations of colors, (iii…

… of color indexing techniques we encode a minimal amount of spatial information in the index.
We … moments of the color distribution and store them in the index. The feature vectors in the …

… We present an efficient color indexing scheme for similarity-based retrieval which has a …
In the following, we present our color indexing technique. Once the color clusters are extracted …

… which in our previous illumination invariant color indexing method [6], [9] was treated as a
mere ordinary gray-scale image in arriving at the 36-D index by use of low-pass scaling and …

… To solve the above problem, we propose to adaptively cluster color images based on human
color perceptions. A 24-bit color image contains up to 16 million colors. Most of the colors …

… In constructing the image database, we have also created a color index hash table (8) for
each image. To retrieve images from the database coded by BTC based on querying by image …

… , we present a theory that explains and supports the performance of the color ratio model
in image indexing, in different color spaces, and when using transformed color features. …

… ted for color angle invariants, color-edge angle invariants and their combination. Three
existing distribution-based techniques--color indexing, color constant color indexing and Healey …
