i have posted multiple concerns regarding Tesseract issues but none of them answered hoping to have some answers this time.

Team please help!!!

Correcting myself EngineMode: LSTMonly and PageSegMode: SparseText

[Shree Devi Kumar]

Why are you using PageSegMode: SparseText?

I get much better results from command line with default psm. See the various types of available outputs - txt, hocr, tsv, alto

Hi, 

Thanks for the reply, i just want to elaborate what i am actually doing will give you a clean picture for a proper guidance!!!

I am using tesseract dll in windows and i am using the below code for engine and page segment mode....

 private static TesseractEngine _engine;

        private static TesseractEngine Engine

        {

            get

            {

                if (_engine == null || _engine.IsDisposed)

                {

                    try

                    {

                        _engine = new TesseractEngine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\tessdata", "eng", EngineMode.LstmOnly);

                    }

                    catch (Exception ex)

                    {

                        ex.Message.ToString();

                    }

                }

                return _engine;

            }

        }

then later i am initializing this engine for reading the text from image:

private string LiftText(Bitmap img)

        {

            string resultText = string.Empty;

            try

            {

                TesseractEngine engine = new TesseractEngine("./tessdata", "eng", EngineMode.LstmOnly);

                Tesseract.Page mypage = engine.Process(img, PageSegMode.SparseText);

                resultText = mypage.GetText();

                mypage.Dispose();

                engine.Dispose();

            }

            catch (Exception ex)

            {

                Exceptioninfo("LiftText()", ex.StackTrace);

            }

            return resultText;

        }

I am using Sparse Text because while reading from the Image some line are parallel with spacing in between attached is the image due to wish i need to forcibly need to go for Sparse Text.

Please suggest me for this.
