Reduce the content of the cells in the

grid to a single point each. By blurring,

then determining the barycenter.

Now deduce the colum (DC) and row distance (DR).

It is an interesting fitting task.

Find and optimal DC and an optimal DR

such that they best predict the observation,

the barycenters of the grid cells.

Please post some examples...

It depends on the context, but finding straight line usually is pretty simple...

Do we have any prior knowledge about the table? Better to have some sample images

hi guys,

i have attached few samples.Please check and tell me

If you still haven't, you can take a look on "A Survey on Table Recognition".

You can try Tesseract OCR by Google, maybe it has something specific for table detection.

If your problem is in the detection, you can do something similar to recursive XY-Cuts.

Or you can train your favourite classifiers to discriminate among text, photos, and tables.

Once you find a table, I think that simple OCR will perform good. Or you can rely on horizontal and vertical projections (just like XY-Cuts does) to find divions among cells.

Again, there are probably already many approaches and many methods. Avoid reinventing the wheel.

Attached is your first example, 'blobified'.

The next step would be to find the barycenter

of each blob.

Now find some nearest neighbors of each

blob and consider the distance to them.

Given an estimated column distance DC and

row distance DR, each blob must have

neighbors in the distance DC, DR,

2*DC, 2*DR, 3*DC, 3*DR, more generally

sqrt((i*DC)^2+(j*DR)^2) for some

integer i,j >= 0.

After you have found optimal DC, DR,

you can proceed to determine the orientation

of the table with simple vector

subtractions.

Thanks Michele and Joachim.

here is same case, kindly get into it

Table drawn output.

Hi Bhaskar Menugula and Sabari Nathan

Can you please let me know how you created grid for non-gridded table.

Thanks in Advance,

Abhishek.
