I am trying to read the below image with the Page Iterator. It reads the
whole page left to right except the very last column titled "Conditional
Payment". I would like some help to tweak my code to fix this. The text for
that column shows up at the end in its own <BLOCK>. For example :
<BLOCK>
Coordination of
Benefits and Recovery
<BLOCK>
Conditional Payment
<BLOCK>
$76.57
$5.56
Also, under "Total Charges", it reads $127.00 as $12700. For some reason it
is not seeing the decimal. and under "Reimbursement Amount", it reads
$76.57 as $76157. It seems to be reading the decimal as a one. Under
"Diagnosis Codes" sometimes it mistakes the commas for decimal. And
sometimes it reads a dollar sign as either a: 5, 3, or 8. Is there any
configuration or training of data or other suggestions to have more
accuracy? Thank you.
Here is my image and following is my page iteration code.
public void iterateOCR(string imgLoc)
{
Rect _pdfRect = new Rect(0, 0, 612, 792); // Entire page - PDF
coordinate system
try
{
using (var ocr = new Tesseract.TesseractEngine(@"./tessdata"
, "eng", Tesseract.EngineMode.Default))
{
using (var img = Pix.LoadFromFile(imgLoc))
{
using (var page = ocr.Process(img,_pdfRect,
PageSegMode.Auto))
{
Console.WriteLine("Text (iterator):");
using (var iter = page.GetIterator())
{
iter.Begin();
do
{
do
{
do
{
do
{
if (iter.IsAtBeginningOf(
PageIteratorLevel.Block))
{
Console.WriteLine(
"<BLOCK>");
}
Console.Write(iter.GetText(
PageIteratorLevel.Word));
Console.Write(" ");
if (iter.IsAtFinalOf(
PageIteratorLevel.TextLine, PageIteratorLevel.Word))
{
Console.WriteLine();
}
}
while (iter.Next(
PageIteratorLevel.TextLine, PageIteratorLevel.Word));
if (iter.IsAtFinalOf(
PageIteratorLevel.Para, PageIteratorLevel.TextLine))
{
Console.WriteLine();
}
} while (iter.Next(PageIteratorLevel
.Para, PageIteratorLevel.TextLine));
} while (iter.Next(PageIteratorLevel.
Block, PageIteratorLevel.Para));
} while (iter.Next(PageIteratorLevel.Block
));
} //using iter
} // using page
} // using img
} // using ocr
}
catch (Exception e)
{
Trace.TraceError(e.ToString());
Console.WriteLine("Unexpected Error: " + e.Message);
Console.WriteLine("Details: ");
Console.WriteLine(e.ToString());}
