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.

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
