Re: [hugin-ptx] Re-arrange image order to fix "blackout" sections

[David W. Jones]

Probably not much help to anyone, but the only times I've encountered 
blacked-out sections were:


1. When I was getting too intricate with inclusion and exclusion masks. 
They were particularly problematic when close to each other.


2. When masks on different images overlap.

3. When watching a stitch run, the log would report a picture not being 
blended. The blend would go fine, I'd note the stitch log's message 
about the photo not being part of the set, or being a duplicate, and 
remove the seeming duplicate. Then I would sometimes get a blacked out 
section. It makes me think sometimes enblend isn't entirely correct when 
it reports *not* blending an image.


This is all with enblend. I've never tried multiblend or felt any need 
to use it.


I use Linux, so can't help if it's Windows-specific.

Re: [hugin-ptx] Re-arrange image order to fix "blackout" sections

[Luís Henrique Camargo Quiroz]

   Hi Rich,

   Some ideas that can help:
   1 - use enblend with the option
--primary-seam-generator=nearest-feature-transform, this maybe is the best
solution in general,
   2 - see if you can modify the amount of superposition between images
(use masks to "cut" and shape excess superposition)
   3 - maybe enblend with --pre-assemble (can be used with solution 1) can
help too.

   Now I rarely face this problem, I hope these ideas help you too!

   bye,

   Luís Henrique

[hugin-ptx] Re-arrange image order to fix "blackout" sections

[Rich MacDonald]

On very large renders (>15K pixels/side), I often see hugin "skipping" an 
image or two and leaving a blank space.

Example at https://photos.app.goo.gl/sEqkSeJbqYSGBGTb8

Rendering at lower resolution fixes the problem.

At full resolution, by trial and error I re-arrange the order of the images 
and keep trying until I get lucky with a version without blanks. Sometimes 
a single re-arrange works. Sometimes a re-arrange just causes a blank 
somewhere else. 

This isn't a new problem. I've been running into it for many years. Anyone 
have a better suggestion of how to deal with it?

Windows platform. Latest release. Plenty of RAM and CPU.
