From: Birdsong classification based on ensemble multi-scale convolutional neural network
Wavelet spectrograms. The WT spectrogram is arranged from top to bottom and from left to right according to the bird number in Table1. The x-axis and y-axis of the wavelet spectrogram represents the time domain and frequency-scale domain respectively, and the color is energy information, the hotter color the more energy is.
