Recognize Text by Performing OCR on Image from URL with Java

Recognize-Text-OCR-Image-using-Java

You can convert a text from the image to an editable format with Optical Character Recognition (OCR). Images like JPG, PNG, TIFF, BMP, GIF, etc. are used everywhere on the internet and you may need to recognize text from an online image. You can easily use the URL link to that image to perform the OCR on it, instead of saving or downloading the file. The following headings discuss the details further:

Recognize Text by Performing OCR on Image from URL with Java

You can perform Optical Character Recognition on an image from URL with the following steps:

  1. Create API instance with AsposeOCR class.
  2. Specify image URI.
  3. Set recognition options with RecognitionSettings class.
  4. Get result object.
  5. Print result.

The following code explains how to recognize text by performing OCR on image from URL programmatically using Java:

Recognize Text from Skewed or Tilted Image with OCR using Java

Sometimes an image can be tilted or skewed for some reason. For instance, an image created by a camera or scanner can be a little skewed, then you can get the skew angle of the input image. You can improve the accuracy of text recognition by knowing and correcting the skew angle. You need to follow the following steps:

  • Create API Instance using AsposeOCR object.
  • Set recognition options.
  • Calculate and set skew angle.
  • Get the result with the RecognitionResult object and print it.

The code below shows how to recognize text from a skewed image with OCR programmatically in Java:
