使用C＃进行OCR读取

Question

我有一个项目，用于读取捕获图像中的字符，但是我被困在用于扫描图像的按钮上。我在c＃中结束了tesseract dll，但我不知道如何编写它。我是这个节目的新手。

 private void Browse_Click(object sender, EventArgs e)
    {
        //FileInfo fi = new FileInfo(string.Format(@"C:\Documents and Settings\JOrce0201610\My Documents\Visual Studio 2005\Projects\OCR Reader\{0}", imageName));
        OpenFileDialog fi = new OpenFileDialog();
        fi.InitialDirectory = @"C:\\Documents and Settings\JOrce0201610\My Documents\Visual Studio 2005\Projects\OCR Reader\Card";
        fi.Filter = "BMP Image|*.bmp";
        fi.FilterIndex = 2;
        fi.RestoreDirectory = true;
        if (fi.ShowDialog() == DialogResult.OK)
        {
            //image file path
            textBox1.Text = fi.FileName;
            //display image in picture box
            pictureBox1.Image = new Bitmap(fi.FileName);
        }
    }
    private void Scan_Click(object sender, EventArgs e)
    {
        Bitmap temp = source.Clone() as Bitmap; //Clone image to keep original image

        FiltersSequence seq = new FiltersSequence();
        seq.Add(Grayscale.CommonAlgorithms.BT709);  //First add  GrayScaling filter
        seq.Add(new OtsuThreshold()); //Then add binarization(thresholding) filter
        temp = seq.Apply(source); // Apply filters on source image

如果你是编程的'新手'，OCR不是最佳起点。我建议的最好的是你使用可以为你做这件事的网络服务或现有的库。

微软有project Hawaii，夏威夷有一个非常容易使用的OCR服务。
