# Image Average Edit Control

The Image Average edit control edit control provides a graphical user interface to the ImageAverageTool, which you use to accumulate a discrete number of images of the same scene and generate an output image where each pixel value represents the average grey value from that location in all the input images. See the topic Image Averaging for more information.

The following figure shows an example Image Average edit control:

See the topic Control Reference for a description of the buttons along the top of the edit control. In addition, the Image Average tool edit control supports the following image buffers:

- The Current.InputImage buffer contains the next image the tool will analyze plus the graphic for the input region.
- The LastRun.AverageImage buffer contains the last average image the tool generated.
- The LastRun.StandardDeviationImage buffer contains the last standard deviation image the tool generated if that option is enabled.
- The LastRun.InputImage buffer contains the last image processed by the Image Average tool along with any graphics you enable from the Graphics tab.
- The LastRun.TransformedRegionPixels contains the affine-transformed image, but only if you have specified Affine Transform for the Region Mode and you have supplied a RectangleAffine for the input region.
