Context

I am trying to create a clothing segmentation module based on U2NET. It works well, but it seems that the frontend is not processing the response correctly.

I used the SAM example and based my module on it - https://github.com/VeyDlin/cvat-clothing-segmentation.

However, I continue to receive an error when trying to create the mask.

Unfortunately we can't help with issues in custom code

[VeyDlin]

The api documentation would be enough for me, what is expected from the function?

[bsekachev]

In case with SAM nuclio only performs image encoding and returns binary blob with image embeddings. These embeddings with user input (mask clicks) are decoded on client using onnx javascript module. You may find decoder code here: cvat-ui/plugins/sam.

In case with other interactors, client expects the following structure:

export interface InteractorResults {
    mask: number[][];
    points?: [number, number][];
    bounds?: [number, number, number, number]
}
