Aspose.OCR for Java


Aspose.OCR for Java is a stand-alone OCR API for Java applications while allowing the developers to perform optical character recognition on commonly used image types. It provides a simple set of classes to control character recognition for various languages including English, French, Spanish and Portuguese. Developers can easily read characters in multiple fonts, rotated images, whole images or parts of images with the ability to apply different noise removal filters before text recognition.

Extract Text from Scanned Document Images

Using the library, developers can extract text, location of the text from specific parts of an image, fonts, and styles as well as perform the character recognition operation on document scans that follow a similar structure. Recognizing text from images is simple, with just a few lines of code.

Perform OCR on image - Java

// create an instance 
OcrEngine engine = new OcrEngine();
// set image file
engine.setImage(ImageStream.fromFile(dir + "template.jpg"));
// process the image
// Image to Text results 

Recognize Text in Popular Fonts & Languages

Aspose.OCR for Java API supports Arial, Times New Roman, Courier New, Verdana, Tahoma and Calibri fonts in regular, bold and italic text styles as well as multiple languages such as English, French, Spanish, and Portuguese

Easy to Use Image Correction Filters

Noise reduction is a typical pre-processing step to improve the results. Using the OCR library, you can apply Blur, Gaussian Blur & Median correction filters on the document image in order to improve the recognition accuracy.

Apply correction filters - Java

// initialize
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
// do processing
