The mask does not exactly coincide with the original image about salt

Yeah, this is an ONNX thing. It can be handled at an application level pretty easily (generate all models corresponding to each resolution for a dataset, pick the model based on resolution). I have added #3 enhancement covering this, closing this issue for now.

[anuragxel]

So this is an artifact of ONNX generator helper. Did you change the resolution of the helper to generate a ONNX model of the resolution of your images? ONNX supports models for a specific resolution.

I would appreciate a PR that can select the right ONNX model based on the resolution of the input (assuming ONNX model name format maybe -- onnx_model_<res>.onnx).

Thank you very much for your prompt reply！I use default resolution of the input as shown blow.
Is there anything that I need to change ?

Yeah, change it to the resolution of your input image and try again? It should work. This is how ONNX models work, they compile the model ops to a specified resolution (and usually it works for multiples of that resolution, which your image probably isn't).

[1191658517]

yes it works nicely now.
this issule(facebookresearch/segment-anything#56) has reported this problem either.
