Fibrosis feature detection.

<p>Masson’s trichrome stained lung sections from study 3, Bleomycin (A, C, E, F) and Saline (B, D, F, H) animals, <b>A and B</b> at low magnification, scale bar 2.5mm <b>E and F</b> alveolar structure at high magnification, scale bar 50μm. Upper right square: zoom in one alveola. <b>C and D</b>: low scale detection model; false colour image indicates areas of dense fibrosis (green), alveolar tissue (blue), bronchi (red), background (yellow). <b>G and H:</b> high magnification detection; false colour image indicates collagen (blue), lung tissue (red), background (yellow). Upper right square: zoom in one alveola collagen detection.
