Prostate cancer detection results on ex vivo MRI data. (a), (e) 2D sections from 3D prostate MRI data, and (b), (f) corresponding CaP masks superposed on the MRI, obtained via deformable registration with the corresponding histology slice (not shown) [50]. Corresponding CaP detection results via (c), (g) Ψ(X _GE ) (graph embedding), and (d), (h) $\mathrm{\Psi }\left({\tilde{\mathbf{X}}}_{GE}\right)$ (consensus embedding) are superposed back onto the original MRI sections ((a), (e)). In each of (b)-(d) and (f)-(h), green denotes the CaP segmentation region. Note the significantly fewer false positives in (d) and (h) compared to (c) and (g) respectively.
