Page segmentation and preserve_interword_space are not working

[Prav]

Hi,

I am trying to extract tabular data. For this I am converting the image into hocr. 

Now this hocr is not coming properly. It first puts the data for one column and then for the other. I do not get data which is put row wise and column wise so that the extraction comes as a proper table.

I have tried with -psm 5 and with -psm 6 but in both cases the hocr looks identical.

I am using tesseract 3.05

even preserve_interword_space set to 1 is not working.

Any help would be useful

For eg

we have the following in the image

Colulmn 1             Column 2

X                           1

Y                           2

Z                           3

hocr is giving

X

Y

Z

1

2

3

I would like the output to be

X     1

Y     2

Z     3

Will be grateful for any help and/or ideas

Thanks

Try  'tsv' instead of 'hocr'

Thanks for the reply.

TSV is giving data in a column. So it covers column1 then column2 and finally column 3 one below the other.

I am not able to figure out how to construct a table from a TSV.
