Constructors
| Name | Description |
|---|---|
| PreprocessingFilter() | The default constructor. |
Properties
| Name | Description |
|---|---|
| static Default { get; } | Default filters collection contain AutoSkew filter |
| static Empty { get; } | Empty filters collection |
Methods
| Name | Description |
|---|---|
| static AutoDenoising() | 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. |
| static AutoDenoising(Rectangle) | Enables the use of an additional neural network to improve the image part - reduce noise. Useful for images with scan artifacts, distortion, spots, flares, gradients, foreign elements. |
| static AutoDewarping() | Automatically corrects geometric distortions in the image. Extremely resource intensive! |
| static AutoSkew() | Enables the automatic image skew correction. |
| static AutoSkew(Rectangle) | Enables the automatic image part skew correction. |
| static Binarize() | Converts an image to black-and-white image. Binary images are images whose pixels have only two possible intensity values. They are normally displayed as black and white. Numerically, the two values are often 0 for black, and 255 for white. Binary images are produced by auto thresholding an image. |
| static Binarize(Rectangle) | Converts a part of the image to black-and-white image. Binary images are images whose pixels have only two possible intensity values. They are normally displayed as black and white. Numerically, the two values are often 0 for black, and 255 for white. Binary images are produced by auto thresholding an image. |
| static ContrastCorrectionFilter() | Contrast correction filter. |
| static ContrastCorrectionFilter(Rectangle) | Contrast correction filter for the part of the image. |
| static Dilate() | Dilation adds pixels to the boundaries of objects in an image. |
| static Dilate(Rectangle) | Dilation adds pixels to the boundaries of objects in a part of the image. |
| static Invert() | Automatically inverts colors in a document image. |
| static Invert(Rectangle) | Automatically inverts colors in a part of the image. |
| static Median() | The median filter run through each element of the image and replace each pixel with the median of its neighboring pixels. |
| static Median(Rectangle) | The median filter run through each element of the image part and replace each pixel with the median of its neighboring pixels. |
| static Resize(int, int) | Rescale image - Upscale or downscale image resolution. InterpolationFilterType = Lanczos8 |
| static Resize(int, int, InterpolationFilterType) | Rescale image - Upscale or downscale image resolution. |
| static Rotate(float) | Rotate original image. |
| static Rotate(float, Rectangle) | Rotate a part of the image. |
| static Scale(float) | Rescale image - Upscale or downscale image resolution. InterpolationFilterType = Lanczos8 |
| static Scale(float, InterpolationFilterType) | Rescale image - Upscale or downscale image resolution. |
| static Threshold(int) | Create a binary image based on setting a threshold value on the pixel intensity of the original image. |
| static Threshold(int, Rectangle) | Create a binary part of the image based on setting a threshold value on the pixel intensity of the original image part. |
| static ToGrayscale() | Converts an image to grayscale image. Grayscale image have 256 level of light in image (0 to 255). |
| Add(PreprocessingFilter) | Add the new filter to the collection to further run all operations. Consistency in the collection matters. |
| GetEnumerator() | For IEnumarable interface realization. |
