Simplest APIs to Perform OCR on Images
With as little as 4 lines of code, you can add OCR functionality to your Java applications. It is really that simple!
Perform OCR on image - Java
// create an instance of OcrEngine OcrEngine engine = new OcrEngine(); // set image file engine.setImage(ImageStream.fromFile(dir + "template.jpg")); // process the image engine.process(); // get results System.out.println(engine.getText());
Scan Whole Image or Portion
Using Aspose.OCR for Java, developers can extract text and related information such as font, style & location of the text from specific parts of an image. This feature allows to perform the OCR operation quickly on document scans that follow the similar structure.
Easy to Use Image Correction Filters
Noise reduction is a typical pre-processing step to improve the OCR results. Using Aspose.OCR, you can apply Blur, Gaussian Blur & Median correction filters on the document image in order improve the recognition accuracy.
Apply correction filters - Java
// initialize OcrEngine OcrEngine engine = new OcrEngine(); // set image engine.setImage(ImageStream.fromFile(dir + "template.jpg")); // create collection of filters CorrectionFilters filters = new CorrectionFilters(); // create & add a few filters to the collection filters.add(new MedianFilter(6)); filters.add(new GaussBlurFilter()); // assign collection to OcrEngine engine.getConfig().setCorrectionFilters(filters); // do processing
Recognize Text in Popular Fonts & Styles
Aspose.OCR for Java API supports Arial, Times New Roman, Courier New, Verdana, Tahoma and Calibri fonts in regular, bold and italic text styles.
Support for Global Languages
Aspose.OCR for Java API supports multiple languages such as English, French, Spanish and Portuguese.
