Fig. 7. Images (a and b), (c and d) and (e and f) were taken from ref. 27, self-drawn and adapted from ChemPix,19 respectively. Img2Mol is in principle able to recognise simple hand-drawn molecules (d–f) without errors, but introduces errors for more complex, larger molecules (a–c). The dashed red line indicates the incorrectly predicted region of the molecule.
