我试图让 OCR 示例应用程序识别一些小文本,而我的做法是调整图像大小。一旦我调整了图像的大小,它都是'pixel-ee'
我想使用SmothGaussian 方法来清理它,但每次执行该方法时都会出错
这是代码:
Image<Bgr, Byte> image = new Image<Bgr, byte>(openImageFileDialog.FileName);
using (Image<Gray, byte> gray = image.Convert<Gray, Byte>().Resize(800, 600, Emgu.CV.CvEnum.INTER.CV_INTER_LINEAR, true))
{
gray.Convert<Gray, Byte>()._SmoothGaussian(4);
_ocr.Recognize(gray);
Tesseract.Charactor[] charactors = _ocr.GetCharactors();
foreach (Tesseract.Charactor c in charactors)
{
image.Draw(c.Region, drawColor, 1);
}
imageBox1.Image = image;
//String text = String.Concat( Array.ConvertAll(charactors, delegate(Tesseract.Charactor t) { return t.Text; }) );
String text = _ocr.GetText();
ocrTextBox.Text = text;
}
这是图像:
