Download link in gen.py not working

[ihph]

1. Hello, I am having trouble creating my own data set. The link to example data seems to be no longer working...
   DATA_URL = 'http://www.robots.ox.ac.uk/~ankush/data.tar.gz'

2. Question related to the textspotter demo http://zeus.robots.ox.ac.uk/textspot/
   Is this demo using your "FCRNall + multi-filt" model ? Is the code for this model available ?

Thank you

1. I'm able to download the file locally. It could be that the server is blocking your requests.
   I've uploaded it to Google Drive here:

2. The demo is using a variant. The code is not available yet.

OK The link you posted in your reply works - I got the data...
Nice work by the way and thank you for open-sourcing !

( another off-topic question: Have you compared your approach to (Text Flow: A Unified Text Detection System in Natural Scene Images : Shangxuan Tian, Yifeng Pan, Chang Huang, Shijian Lu, Kai Yu, Chew Lim Tan
https://arxiv.org/abs/1604.06877 - I'm trying to choose which one to reproduce... )
Re-read the papers..you get better recall and they get better precision, but end up with f = 80.25 in icdar2013 - I'll try to reproduce your approach thx

Great. Thank you!

@ankush-me Hello,I download data from Google Drive.But when i run gen.py,it have TypeError：

I don't know how to fix it.Can you help me ?
Thanke you

[ankush-me]

It seems that the update to NumPy breaks indexing by floats.
You just need to cast the floats (change line 259 in synthgen.py to the following):

place_mask = 255*np.ones((int(np.ceil(COL))+pad,int(np.ceil(ROW))+pad),'uint8')

@ankush-me Thanks，it can work now.And if want to create my own data set,I must do that:

1. Use depth-from-single image ConvNets to create depth image
2. Use Holistic Edge Detection to create segmentation image
3. Use h5py to save to dset.h5

is it?

[ankush-me]

Yes, correct.
