C#调用IronOcr识别文字不理想
识别文字不理想，不知道什么原因，文字太小就几乎无法识别。。。。
void Test()
{
DateTime d1 = DateTime.Now;
var ocr = new IronTesseract();
ocr.Language = OcrLanguage.ChineseSimplifiedBest;
//ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
using (var ocrInput = new OcrInput())
{
ocrInput.AddImage("D:\\1.png");
// ocrInput.AddPdf("document.pdf");
// Optionally Apply Filters if needed:
//ocrInput.Deskew(); // use only if image not straight
//ocrInput.DeNoise(); // use only if image contains digital noise
ocrInput.Invert();
//ocrInput.ToGrayScale();
ocrInput.EnhanceResolution();
var ocrResult = ocr.Read(ocrInput);
var useSeconds = (DateTime.Now - d1).TotalMilliseconds;
Console.WriteLine("" + useSeconds + ":" + ocrResult.Text);
}
}
fffffffffffffffff
test red font.
