Hoku is an image processing software
Hoku is used to process multispectral image data sets to recover writings that have been damaged or erased. It is a Java-base software package distributed free-of-charge, without warranty.
Hoku is a batch processing software package. Jobs are defined and parameters are set interactively with a graphical user interface, but jobs are run in batch mode until they conclude.
There are no interactive image processing methods available. You cannot touch-up or draw on an image with this software, but you can apply any of several image processing methods to enhance image details that otherwise are difficult to see.

New Features in version 2.3
Three new modules were added to the Cupboard, ImFill, Pause, and WriteStack.
ImFill replaces outlier values, within a window, with that window’s average value.
Pause is used in a flowchart to introduce a short delay. WriteStack will write out several images, one for each band of the input image.
One major change on Hoku for Macintosh computers, is that the new Mac version of Hoku will run on both a computer with an M-chip, or the older Intel chip. As a result, there is now only one version of Hoku for the Mac. There is also only one version for Windows. A Linux version is under development.
