Cause

Yes, it is possible to extract text from images (PNG, JPEG, TIFF, AFP) using Aspose. The Aspose.OCR library is specifically designed for this purpose. If you’re experiencing difficulties in extracting text, it may be due to factors such as image quality, OCR settings, or the specific format of the image.

Solution

To extract text from images using Aspose.OCR in Java, you can follow this sample code:

Code

import com.aspose.ocr.*;

public class OcrExample {
    public static void main(String[] args) {
        // Create an instance of OcrEngine
        OcrEngine ocrEngine = new OcrEngine();

        // Load the image file
        ocrEngine.setImage(ImageStream.fromFile("path/to/your/image.png"));

        // Perform OCR
        if (ocrEngine.process()) {
            // Get the recognized text
            String recognizedText = ocrEngine.getText().getText();
            System.out.println("Recognized Text: " + recognizedText);
        } else {
            System.out.println("OCR processing failed.");
        }
    }
}

Make sure to replace "path/to/your/image.png" with the actual path to your image file.

Next Steps

  1. Ensure that the image quality is good; low-quality images can lead to poor OCR results.
  2. Experiment with different image formats if you’re not getting satisfactory results.
  3. Check the Aspose.OCR documentation for additional settings that might improve recognition accuracy.

If you follow these steps and still encounter issues, please provide more details about the specific problems you’re facing, and I will assist you further!

Would you please try adding onnxruntime 1.20.0 JAR in your project? In case you are working with Maven, you can use below dependency in pom.xml:

<!-- https://mvnrepository.com/artifact/com.microsoft.onnxruntime/onnxruntime -->
<dependency>
    <groupId>com.microsoft.onnxruntime</groupId>
    <artifactId>onnxruntime</artifactId>
    <version>1.20.0</version>
</dependency>
