Contrast correction

[ ]

Low contrast and blurring are the most typical distortions when text is photographed with a smartphone camera, especially in low light conditions. They make it difficult for the OCR algorithms to operate successfully, significantly reducing the recognition accuracy.

Aspose.OCR Cloud can automatically increase the contrast of images before proceeding to recognition. Set the makeContrastCorrection recognition setting to true to enable the automatic contrast adjustment. This setting is available for all image recognition methods.
