2004 RGB A STUDY OF RGB COLOR INFORMATION AND ITS APPLICATION 03R3237
Abstract This paper concerns with a method of dynamic image cognition. Our image cognition method has two distinguished features. One is that the image is handled as its Eigen (characteristic) pattern and time series frequency characteristic. The other is that the cognition is carried out by solving for the ill-posed linear system of equations comprising the Eigen patterns and time series frequency characteristic as a database. The Eigen pattern consists of histograms in RGB color components of the image. This Eigen pattern of color components yields a numerical data set which is hard to be changed by the differences in spatial position of target as well as resolution of the image. The time series frequency characteristic consists of Fourier power spectra of time changing Eigen patterns. This time series frequency characteristic is a distinct frequency characteristic to each of the objects. The image cognition method proposed in this paper is composed of the Eigen pattern and time series frequency characteristic. As a result, it is revealed that the method proposed in this thesis is one of powerful and effective methods of dynamic image cognition. 1
