Frequently Asked Questions

What types of prompts does Segment Anything support?

Segment Anything supports a variety of prompts, including foreground/background points, bounding boxes, and more. Text prompts are also discussed in research but are not yet released.

How is the model structured?

The model consists of a ViT-H image encoder, a prompt encoder to process inputs, and a lightweight mask decoder to predict object masks from embeddings.

What platforms can the model run on?

The image encoder requires a GPU and is implemented in PyTorch. However, the prompt encoder and mask decoder can also run on CPU across various platforms via ONNX runtime.

How long does inference take?

Inference with the image encoder takes approximately 0.15 seconds on an NVIDIA A100 GPU, while the prompt encoder and decoder take around 50 milliseconds on a CPU within a web browser.

Does Segment Anything work on videos?

Currently, Segment Anything only supports images or individual frames rather than video sequences directly.

Where can I find the code for Segment Anything?

The code for Segment Anything is publicly available on GitHub for those interested in exploring or contributing to its development.
