PDF Image Enhancement Results

IronOCR offers unique filters for OcrInput objects to enhance PDF input performance.

Example Image Code Enhancement

Enhancing input quality allows for higher accuracy and faster OCR processing.

using IronOcr;

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Latin;

using (var Input = new OcrInput(@"LowQuality.jpeg"))
{
    // Improve image readability
    Input.DeNoise(); // Clean up noisy data
    Input.Deskew(); // Align the image correctly
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

using IronOcr;

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Latin;

using (var Input = new OcrInput(@"LowQuality.jpeg"))
{
    // Improve image readability
    Input.DeNoise(); // Clean up noisy data
    Input.Deskew(); // Align the image correctly
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
}

Imports IronOcr

Private Ocr = New IronTesseract()
Ocr.Language = OcrLanguage.Latin

Using Input = New OcrInput("LowQuality.jpeg")
	' Improve image readability
	Input.DeNoise() ' Clean up noisy data
	Input.Deskew() ' Align the image correctly
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
End Using

Imports IronOcr

Private Ocr = New IronTesseract()
Ocr.Language = OcrLanguage.Latin

Using Input = New OcrInput("LowQuality.jpeg")
	' Improve image readability
	Input.DeNoise() ' Clean up noisy data
	Input.Deskew() ' Align the image correctly
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
End Using

Summary of available input enhancement filters

OcrInput.Rotate(double degrees): Rotates images clockwise by the specified degrees. Use negative values for anti-clockwise.
OcrInput.Binarize(): Converts the image to black and white, useful for high-contrast OCR cases.
OcrInput.ToGrayScale(): Converts image pixels into grayscale to improve OCR accuracy.
OcrInput.Contrast(): Increases contrast to improve text readability.
OcrInput.DeNoise(): Removes digital noise to clean up the image.
OcrInput.Invert(): Inverts all colors, turning black to white and vice versa.
OcrInput.Dilate(): Adds expansion to object boundaries, useful for dilating thin text.
OcrInput.Erode(): Reduces the boundary of objects, the opposite of dilate.
OcrInput.Deskew(): Corrects image tilt, crucial for OCR accuracy when skew exceeds 5 degrees.
OcrInput.DeepCleanBackgroundNoise(): Advanced noise removal for heavily distorted documents.
OcrInput.EnhanceResolution: Automatically upscales images with low DPI for better recognition.

Additional advanced settings in the OCR process aim to leverage unique IronOCR capabilities for optimal text scanning results.
