How to implement attack in single-chennel dataset

[outouser]

Thank you for open-sourcing the code.I wonder how to perform attacks on single-channel datasets such as MNIST and Fashion-MNIST? Additionally, how does the selection of POOD apply in these cases?
Thank you for your time and assistance.

For a single-channel dataset attack, I think is fine to use the same pipeline to generate the trigger by changing the model input to a single channel. For the dataset, as MNIST is a subset of the NIST dataset, use can use the other subset from the NIST dataset, or some similar datasets like EMNIST, USPS, etc.
