Color-Based Image Similarity
Color plays an important role in content-based image retrieval. In this chapter we define color features in an appropriate, perceptually uniform color space, where color distributions describe the contents of entire images. Summarizing these distributions by color signatures and using the Earth Mover’s Distance leads to a powerful color-based retrieval paradigm. Combining the color information of the pixels, with their positions in the image leads to a distance measure where not only the color contents matters but also the layout of the color in the image.
