Sign Segmentation: Include Sign Segmentation Model

[AmitMY]

Problem

Given a pose sequence, we would like to perform two types of segmentation.

Sentence segmentation - every sentence should be then translated independently.
Sign segmentation - every sign in a sentence should be transcribed to SignWriting independently.

Description

We currently have such a segmentation model https://github.com/sign-language-processing/transcription/tree/main/pose_to_segments
Which works reasonably well for sentences, but not at all well for signs.

Should perhaps look into developing an autoregressive model like https://arxiv.org/pdf/2301.02214.pdf

That way, we could also perform this live.

Alternatives

Use the existing model, which is bi-directional, and will require re-running on the sequence every single time.

We are done with our segmentation model:
https://arxiv.org/abs/2310.13960

We should integrate it by doing:

1. Removing free camera support - user should be able to stop and restart the camera

2. We perform pose estimation, and segmentation. Segments are stored as an array-of-arrays - sentences, and within them signs.

3. Segments are shown in multiple ways:

   • SignWriting (future work)
   • images (first frame + last frame + arrow of movement if exists) ideally like this
     

4. When hovering a segment, the video plays in a loop only of that segment
