TimeBridge ViT-S/8

Pretrained ViT-S/8 checkpoint for TimeBridge: Self-Supervised Video Representation Learning via Start-End Joint Embedding and In-Between Frame Prediction.

This repository provides the official TimeBridge pretrained model checkpoint used for self-supervised video representation learning.

Model

Backbone: ViT-S/8
Training epochs: 400
Framework: PyTorch
Checkpoint file: timebridge_vits8_400ep.pth

Overview

TimeBridge learns video representations by modeling the temporal evolution between a start frame and an end frame, and reconstructing intermediate frames as a self-supervised training signal.

The learned features are designed for dense video understanding tasks such as:

video object segmentation
semantic propagation
part propagation

Usage

Load the checkpoint in PyTorch:

python

import torch

ckpt = torch.load("timebridge_vits8_400ep.pth", map_location="cpu")
print(ckpt.keys())
