]RecognitionSettings class
Settings for the image recognition.
Contains elements that allow customizing the recognition process.
The RecognitionSettings type exposes the following members:
Constructors
| Name | Description |
|---|---|
| RecognitionSettings() | Initializes a new instance of the |
| RecognitionSettings(auto_skew) | Initializes a new instance of the RecognitionSettings class |
Properties
| Name | Description |
|---|---|
| threads_count | Gets or sets the number fo threads for processing. By default, 0 means that the image will be processed with the number of threads equal to your number of processors. ThreadsCount = 1 means that the image will be processed in the main thread. |
| auto_skew | Gets or sets a flag indicating whether automatic image skew correction should be enabled. Enabled (true) by default. |
| skew_angle | Gets or sets angle in degrees for image rotation. |
| language | Gets or sets the language used for OCR. Determines the alphabet used during recognition. Multi-language by default. |
| threshold_value | Gets or sets custom threshold value for image binarization. Range from 1 to 255. |
| ignored_symbols | Sets blacklist for recognition symbols. |
| ignored_characters | Sets blacklist for recognition symbols. |
| allowed_symbols | Set the allowed characters with alphabet property. |
| lines_filtration | Allows to recognize text in the tables (regions surrounded lines). |
| preprocessing_filters | Allows to prepare the image for OCR by adjusting pre-processing methods. |
| auto_contrast | Allows using an additional contrast correction algorithm for the image before recognition. |
| allowed_characters | Allowed characters set. Determines the type of characters allowed for recognition result. |
| detect_areas_mode | Allows to select the optimal mode for document type areas: document, photo, plain text, column, image. |
| auto_denoising | Enables the use of an additional neural network to improve the image - reduce noise. Useful for images with scan artifacts, distortion, spots, flares, gradients, foreign elements. |
| automatic_color_inversion | Detect images with white text on dark/black background and automatically choose a special OCR algorithm for them. |
| upscale_small_font | Allows you to use additional algorithms specifically for small font recognition. Useful for images with small size characters. |
