Decomposition errors depending on SNR and number of modes for 100 × 100 input image: a amplitude error, b phase error, c net error, and d intensity error. Horizontal axes correspond to the number of modes and vertical axes correspond to SNR in dB. Decomposition error values are color-coded, regions with an error value less than a certain value are labeled on the graphs. Here εA—amplitude error, εφ—phase error, εNET—total error, and εI—intensity error. Source data are provided as a Source Data file.
