Normalize Image

The Normalize Image command adjusts the image luminance to match a target specification, such as a specific value or a statistical luminance inside a region. A common application of this command is to match the brightness (luminance) of an image set. This dialog has two forms: a general form accessible as a menu command, and a specific form for a displayed image set that opens from the Animation Bar and processes only that specific image set. Normalize Image Set is opened only from a displayed image set; Normalize Images can take source images from an image set of files.

Open the Normalize Image command from theProcess > Math menu. or open from the Animation Bar on an Image Window. The Normalize Image Set dialog is opened from the Animation Bar.

Normalize Image Properties
Profile [\|>]	Opens the Select Source Images dialog to choose images from an image window, folder, files, pattern, or a file list.
[Select]	Select the source images.
Normalization Target
Image	Selects normalization to a statistic computed from a reference image.
[Select]	Selects the normalization target image from an image window, folder, file, pattern, or a file list.
Value	Selects normalization to a value. The value is entered in the field to the right. Use the [+] and [x] buttons to add or delete the currently displayed entry.
Image Normalization	Selects the method used to adjust the pixels during the normalization process. Offset adds a constant to the image values. Scale multiplies the image values.
Normalization Stat...	Click this button to open the Region Statistics dialog to set Properties for computing a region statistic on the images.
Adjust Exposure Time	Check this box to adjust the exposure time to correspond to the image luminance after normalizingScale method.
Output Pixel Type	Select the numeric pixel type in the normalized images.
