Amplitude phase time-frequency diagram expression method based on LAB color space mapping

The invention discloses an amplitude phase time-frequency graph expression method based on LAB color space mapping, which comprises the following steps of: performing short-time Fourier transform on a time domain signal and then taking an amplitude value and a phase value so as to obtain an initial amplitude matrix and an initial phase matrix; performing piecewise linear companding processing on the initial amplitude matrix to obtain a first amplitude matrix; performing difference sine and cosine transformation on the initial phase matrix to obtain a first phase matrix and a second phase matrix, and obtaining a group of three-channel data formed by the first amplitude matrix, the first phase matrix and the second phase matrix; mapping the obtained three-channel data to an LAB domain to obtain three-channel time-frequency domain matrixes L, A and B in an LAB color space; and converting the three-channel time-frequency domain matrixes L, A and B into an RGB domain to generate a visual time-frequency ...
