ImageProcessing()
public ImageProcessing()
Render(OcrInput images)
public static OcrInput Render(OcrInput images)
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:
| Parameter | Type | Description |
|---|---|---|
| images | OcrInput | OcrInput object containing different images @see #OcrInput. |
Returns: OcrInput - OcrInput object containing result processed images @see #OcrInput in Image field.
