ABE/History explorer forget mask

[georg.viehoever]

Hi,

I am setting a mask before applying an ABE. The history explorer does not record that ABE is applied with mask. Actually, i think the real bug here is that ABE does not honor masks at all, even if you apply the model to the masked image.

Hi Georg,

ABE is not a maskable process, so this is normal behavior.

However, it's true that there's no (easy) way to know whether a particular process is maskable or not, and this is indeed a problem. Version 1.5 makes these things clearer (I hope) thanks to a redesigned Process Explorer.

Why not enable masking for ABE, at least for the "pixelmath" part of it? Would be more consistent.

Hi Georg,

Without having looked at ABE's source code for a long time (which makes any assertion risky), I agree with you. This process was first designed and implemented by Carlos Milovic back in 2005, as a command-line utility using an early version of the PCL. We implemented it as a PixInsight module in 2006, and if I can remember well, the last revision was made in 2007. That means that this tool isn't up-to-date with respect to most processing tools.

I'll try to update ABE as soon as possible, and I see no a priori problem to implement masking for the correction phase of the process. If correctly applied, ABE is a very efficient tool for gradient removal in relatively simple cases; it definitely deserves a complete revision.
