A Simulation Environment Utilizing Three-Dimensional Frequency Spectra for the Analysis of Television Coding Techniques
This paper describes the theoretical and technical details of a versatile simulation environment for the development, analysis, and comparison of television coding techniques. The main requirement the system satisfies is the ability to efficiently process three-dimensional images, i.e., video sequences, and to represent them in both the image domain and in the spatiotemporal frequency domain as three-dimensional spectra. By using the three-dimensional spectra of the luminance (Y) and chrominance (U, V) output signals, spectral information representing the two major parameters of analog television, spatiotemporal resolution and cross effects between the luminance and chrominance signals may be obtained. In addition the system is also capable of carrying out a detailed assessment of nonlinear effects, e.g., aliasing, caused by enhanced television coding techniques. By using the frequency response of the eye, an objective and quantitative comparison between different coding methods is possible.
