Schematic of wavelet weighted ensemble (WWE) for one low pass sub-band (LL sub-band) and three high pass sub-bands (LH, HL, and HH) based on discrete wavelet transform (DWT) and inverse discrete wavelet transform (IDWT). (a) Original image. (b) Binary tissue mask. (c) Initial wavelet weights. (d) Additional parameters. ε = 0.1, W1 = 2.1, W2 = 1.8, W3 = 1.8, and W4 = 3.0. (e) Raw probability map for each sub-band. (f) Final probability map. (g) Overlaid image.
