Bispectrum analysis energy feature maps of a malignant patient and analysis of their differences. (A-D) are four types of bispectrum analysis energy feature maps of a malignant patient with breast tumor. (E) The overlapping histogram results of four bispectrum analysis energy feature maps of BS_S1, BS_S2, BS_S3, and BS_A. (F) The mutual information (MI) between each two of the four new bispectrum analysis energy feature maps. (G) The root mean square error (RMSE) between each two of the four new bispectrum analysis energy feature maps.
