Introduction of frequency image and applications

We introduce a new imaging method of "Frequency Image" and its applications. This new image is made from multi-dimensional features of an image and presents a distribution of the frequency of feature vectors. Especially, selecting R, G and B colors as the three features of an image, Frequency Image is a feature image of which pixel represents the frequency of the same color pixels. In this paper, first, we explain the basic idea and how to make this Frequency Image. Next, we introduce some effective applications using this image. Finally we mention excellent potentials of Frequency Images.
