Thresholds Filters
Thresholds your images by different ways:
|
| Threshold Binary |
All pixels lighter than the threshold are converted to white; all pixels darker are converted to value. |
| Threshold To Zero |
All pixels lighter than the threshold are equalized to value; all pixels darker are not converted. |
| Threshold Truncate |
All pixels lighter than the threshold are not converted; all pixels darker are equalized to threshold. |
Binary
Threshold Binary filter converts grayscale or color images to a high-contrast, black-and-white images. The user can specify a certain level as a threshold. All the pixels lighter than the threshold are converted to a white and all the pixels darker than the threshold are converted to a value. Threshold Binary filter is useful for determining the lightest and darkest areas of the image.
To use the Threshold Binary filter: Choose Filters > Thresholds > Binary.
Threshold To Zero
The user can specify a certain level as a threshold. All the pixels lighter than the threshold are equalized to a value; all the pixels that are darker are not converted.
To use the Threshold To Zero filter: Choose Filters > Thresholds > To Zero
Threshold Truncate
The user can specify a certain level as a threshold. All the pixels lighter than the threshold are not converted; all pixels that are darker are equalized to the threshold.
To use the Threshold Truncate filter: Choose Filters > Thresholds > Truncate
