よくある質問
Is portrait detection performed on the device?
The verified workflow uses an on-device portrait model after its required model asset is available.
Will every edge be detected perfectly?
No. Hair, low contrast, complex backgrounds, and image quality can affect the generated mask, so preview review is required.
