如何通过 Aspose.OCR 提高低质量图像的 OCR 准确性

using Aspose.OCR;

RecognitionSettings settings = new RecognitionSettings();
settings.AutoContrast = true; // Improve contrast automatically
settings.Denoising = true;    // Remove background noise
settings.Deskew = true;       // Correct rotated images
settings.Binarization = true; // Convert to black/white for clarity

settings.Language = Language.English;
settings.DetectAreasMode = DetectAreasMode.PHOTO; // If image is a photo

OcrInput input = new OcrInput(InputType.SingleImage);
input.Add("blurry_invoice.jpg");
AsposeOcr ocr = new AsposeOcr();
List<RecognitionResult> results = ocr.Recognize(input, settings);
foreach (RecognitionResult result in results)
{
    Console.WriteLine(result.RecognitionText);
}

foreach (string file in Directory.GetFiles("./problem_images", "*.png"))
{
    input.Add(file);
}
