Lucid Data Dreaming

Lucid Data Dreaming for Multiple Object Tracking, A. Khoreva, R. Benenson, E. Ilg, T. Brox and B. Schiele, arXiv preprint arXiv:1703.09554, 2017.

TEASER

Lucid Data Dreaming is a data augmentation technique for semi-supervised video object segmentation (pixel-level object tracking). It generates in-domain training data using the provided annotation on the first frame of each video to synthesize (“lucid dream”) plausible future video frames. This data augmentation allows us to train high quality appearance- and motion-based models for pixel-level tracking while using 20×∼100× less annotated data than competing methods.

Check our visit our project page for pre-computed results on DAVIS 2016, DAVIS 2017, results visualization, and additional information.

Usage

  • To synthesize new images with lucid data dreaming, see lucid_dream.m
  • For demo about how to use this function, see demo.m

luciddatadreaming's Issues

Abount the running time

hi ankhoreva,
Thank you for your public code for LucidData!
When I running the "demo", i found the fuction " [im1, gt1, prev_mask1, im2, gt2, prev_mask2, Flow_B, Flow_F]= lucid_dream(img,gt, 1); " run about 160 second.
is that right? or anything setting to improve the speed?

How many image pairs?

Hi,

Thanks a lot for providing the codes!

How many image pairs are generated per-video using the first frame and its annotation?

Where is run.py

Dear,

How can I get the Lucid Data Dreaming by my python 3.7 code? I saw here all of Matlab source, could you tell me how can I run by my python code?

Thanks in advance
