AA6 Mask functions

Post by Forum_2016 »

I am trying to use the new AA6 mask functions. It seems very easy to select a part of an image and get statistics or a separated mask image. Is not clear to me how to apply filters to the selected areas and merge back in a final image. Any suggestion? Thanks.

There is no need to merge, the filter is simply applied to the masked region (be careful to select a Mask, not just a simple Selected Rectangle). There are 3-4 filters which are not directly compatible with masks (Gradient, DDP, etc) because they need to change the visualization of the whole image. In this case you can still process a part of the image, using a manual merge with the original image, after the filter and an histogram stretch.
