Magnetic resonance cholangiopancreatography image enhancement for automatic disease detection

Figure 1 Lazy-snapping graph-cut identification of the significant biliary structures. A: Original magnetic resonance cholangiopancreatography thin slice image; B: Interactive identification of foreground and background, with the corresponding object boundaries identified by the algorithm; C: Silhouette of the identified objects.

Figure 2 Dynamic thresholding through histogram analysis to identify significant biliary structures. A: Original projection-type magnetic resonance cholangiopancreatography image; B: Intensity histogram of the image; C: Resulting thresholded image, rescaled to a 0-255 intensity level.
