Conversion process of cine images to “late gadolinium enhancement (LGE)-like” images. (1) The original cine image is cropped/padded to a square and contrast-limited adaptive histogram equalization (CLAHE) is applied. (2) Cine images are further transformed by first generating a pseudo-enhancement (“LGE-like” enhanced myocardium) mask. (3) Pseudo-scar mask is randomly eroded and Gaussian filters are applied to realistically blur the edges. (4) Speckle noise is added to the image to resemble LGE noise. (5) An LGE cardiac magnetic resonance scan is sampled at random and a histogram match is performed.
