train-bpnet-lines.lua

[shouro chowdhury]

in line number 30 of train-bpnet-lines.lua:
print '     <dataset> - a list of "image_path text_path segmentation" lines'
                                                                                 ????

my questions is what data should i provide for "segmentation" to build the dataset.

I think this is a new approach of training using a line of image with proper transcription. In this approach "image_path" may be the main image to be trained, "text_path" may be the transcription and segmentation may be the segmented color image generated from the main image. However this is my prediction. 

Any explanation from the developers of this approach will help us to test this. Hope you will get the correct answer soon.

Dear Shouro Chowdhury,

There is some information here :
http://sites.google.com/site/ocropus/documentation/recognition-and-training
in the "Training Bpnet Models from Lines" section.

You must be able to provide a segmentation of your input images and
also transcription.
It's quite similar to the training on isolated characters (http://
sites.google.com/site/ocropus/documentation/isolated-character-
training)

Dear Shouro Chowdhury

It seems that openfst is not installed or not detected when the script
is executed. I've added an assert in the script. It doesn't solve the
problem yet, but we will work on it.

I forget to say that you have also now a script rec-line.lua which can
be used to recognize a line

usage: ocroscript rec-line <line> <bpnetfile>

You only have to provide an image of your line and a trained bpnet
(trained on lines)

Dear Yves,
                thanks for the information. We are testing that file and I hope souro will let you know the feedback.
