A Visualization Scheme for Complex Spectrograms with Complete Amplitude and Phase Information

Abstract: We present a novel visualization scheme for complex spectrograms of speech and other non-stationary signals, in which both the amplitude and phase information is visualized simultaneously using the conventional RGB (red, green, blue) color model. The three-layer image matrix is constructed in such a way that the absolute values of the real and imaginary parts of the time-frequency analysis of speech are used to fill the first (red) and third (blue) layers, respectively, and an encoding scheme is adopted to rep… Show more
