Illumination Correction

Group (Subgroup)

ITKImageProcessing (Processing)

Description

This filter takes a series of grayscale images (8 bit or 16 bit) in a given set of Data Containers averages them. The image content only contributes to the average if the value at a given pixel is between the lowest and highest allowed image value set by the user. The user can optionally apply a median filter to the resulting background image. The user can optionally apply the background correction to the input images. The user can optionally export the corrected images to a directory on the file system.

If the user selects Subtract Background from Current Images, the background will be subtracted, and new image data will be created.
