IPBinarizeLceFactor Property

Description

Gets the local contrast enhancement value set by the last call to the Binarize or AutoBinarize method.

Property Type

Read-only property

Syntax

Visual Basic
Public Property IPBinarizeLceFactor As Long

Return Type

The local contrast enhancement.

Valid range is from 0 to 255.

A setting of 0 for this value means local contrast enhancement was not performed.

Values from 1 to 255 control the sensitivity of local contrast enhancement to faint features; lower values yield less sensitivity.

Remarks

This pre-processing operation increases the contrast in each region of the image. When used as a prelude to binarization, usually by setting the 'Binarize Mode' to BIN_MODE_QUICK_TEXT, it increases the sensitivity of the binarization to detail in all regions of the image.

The AutoBinarize method will set this value based on what it determines was the optimal setting for the image during the call. If you have similar images, you can call the Binarize method using this value as well as the other values set by the AutoBinarize method. This will be significantly faster than calling the AutoBinarize method for each image.

Note: This value is also set with the value that is passed into the Binarize method. If you call the Binarize method with some other value, this property will reflect that new value.

This property is read-only at run time and is not available at design time.
