CustomBinarizationFilter

All Implemented Interfaces:

android.os.Parcelable
```
public final class CustomBinarizationFilter
extends ParametricFilter
                    
```
Automatic binarization filter. This filter is a good starting point for most use cases.

CustomBinarizationFilter(BinarizationFilterPreset preset, OutputMode outputMode, Float denoise, Integer radius)
```
- Method Detail
  - getPreset
```
 final BinarizationFilterPreset getPreset()
```
    Preset of binarization filter parameters that are found to perform well on different types of documents.
  - getOutputMode
```
 final OutputMode getOutputMode()
```
    Output mode of the filter. BINARY will return a black and white image, GRAYSCALE will return an antialiased grayscale image.
  - getDenoise
```
 final Float getDenoise()
```
    Value controlling the amount of noise removal. Value between 0 and 1. Too little noise removal may result in a very noisy image, worsening readability. Too much noise removal may result in the degradation of text, again, worsening readability.
  - getRadius
```
 final Integer getRadius()
```
    Filter radius. The bigger the radius, the slower the filter and generally the less noise in the result. The radius is used for both shadows removal and the calculation of local statistics in the main body of the filter. Higher radius usually allows to cope better with regions of light text on dark background. All the values larger than 512 are clamped to 512.
