Method Detail

Save

public static OcrInput Save(OcrInput images,
                            String folderPath)
                     throws AsposeOCRException

Use image processing to improve the accuracy of OCR. Create a list of filters that will be applied to the input image in the order you specify. Example to create filters: PreprocessingFilter filters = new PreprocessingFilter(); filters.add(PreprocessingFilter.AutoDewarping()); filters.add(PreprocessingFilter.Invert()); filters.add(PreprocessingFilter.Threshold(150)); filters.add(PreprocessingFilter.Binarize()); filters.add(PreprocessingFilter.Rotate(180)); filters.add(PreprocessingFilter.Scale(6f)); filters.add(PreprocessingFilter.Dilate()); You don't need all of them. Set only what you need.

Parameters:

images - OcrInput object containing different images @see #OcrInput.

folderPath - Path without image names for saving processed images.

Returns:

OcrInput object containing result processed images @see #OcrInput.

Throws:

AsposeOCRException - if file not found, resource not found or recognition error.
