To the best of our knowledge, no prior model can convert a 3D molecular set photo into its digital structure representation. However, there are some models for 2D structure formulas. The two most recent ones are SwinOCSR and DECIMER.ai . These two models are very similar in architecture, consisting of an image encoder and a transformer. The architectures of DECIMER.ai and SwinOCSR are shown in Figure . ChemPix is another model that attempted to recognize handdrawn hydrocarbon structures using CNN and Long Short-Term Memory (LSTM).
