PTStitcher...

[Ken Warner]

Hi,

I see that I can also use PTStitcher. Reading from the PanoTools wiki I
see that nona is a PTSticher replacement with slightly less functionality.

I'm curious to try PTSticher because when I select it in the pulldown menu
on the sticher tab in hugin, I see some features I'd like to try. Exposure correction in particular

Does nona have exposure correction?

The wiki suggests the mirrors to get PTStitcher but are those the places to
go to get the latest version? Also, I have Hugin 0.7 beta 4 (the About splash
screen says Hugin 0.7 beta 3) with pano13 library. Is the available version
of PTStitcher compatible with pano13?

Or should I forget the whole thing?

Yes, better than PTstitcher.

I rewrote PTstitcher (and called PTmender). It supports all features
in PTstitcher (regarding mapping, including morphing, if I remember
correctly) but some of its functionality is split into several
programs: PTblender, PTroller, and PTtiff2psd.

For large images PTmender is significantly faster than nona due to its
one-line-at-a-time processing.

ptstitcher only works with pano12.

Except that the functionality that you may need for a standard
panorama is already in nona...

The wiki gives the following differences between nona and PTStitcher:
* Morph to fit control points are not supported. (not used by hugin)
* It doesn't yet support the fast transformation option added to
pano12 by Fulvio Senore.
* It doesn't support the adaptive filtersize anti-aliasing filters
added to pano12-2.7.0.11 (useful if you create your panoramas
downsized)

The latest versions of hugin have something much more (read, many
orders of magnitude ;-) more powerful than the exposure correction in
PTStitcher.

This would be the easiest... :-) except of course if you need the extra features
See http://wiki.panotools.org/Nona for the advantages of nona:
# When set to use cropped TIFF output, nona doesn't perform expensive
transformation calculations for unused areas of output images. For
panoramas consisting of many source photos this can speed things up
greatly.
# nona implements vignetting, white-balance, brightness and camera
response curve correction at the stitching stage.
# multi-threaded processing uses as many CPUs as are available.
# nona supports HDR images for input and output.
# nona can merge 8bit low dynamic range bracketed shots into HDR output.

Cheers,

Seb

Including morphing? Would be nice if hugin supported this. For all my
handheld panoramas.
Several Programs: To be honest I never really understood which program
does what. Neither if they are used by hugin or if they provide
additional functions to be used from command line only.

Only PTroller seems to be missing there, couldn't find it elsewhere in
the wiki.

What does PTRoller?

Roller as in Steam Roller. PTRoller flattens many TIFFs into 1 TIFF file.

At the end of December, I added to all the tools, resource files, that
contain version information, that includes a description. If the tools
are built using the Visual Studio projects the resource files are
included in the build. The make files have *not* been updated to
include these resource files. Having the resource file with version
info allows to hover the mouse over the executable and get a popup
tooltip that includes the description. On Windows XP and later at least.

...applying alpha masks I suppose...

All the old tools used three capital letters (PTStitcher,
PTOptimizer, PTViewer, PTEditor) whereas all the new ones only use
capital PT. Hence PTroller can be read P Troller. I don't think this
is intended ;-)

The wiki lacks an overiew over all those tools. Unfortunately I don't
know much about the new tools... Anyone dare to start some pages?
I'll be happy to glossarify and categorize them...

[Ken Warner]

Thanks Daniel, Seb, Joachim, Carl, Erik, Jim,

Ok, so I'll just continue to use what's in Hugin 0.7 beta 4
for now.

I'll wait until the next release. I always like to be
the last penguin off the ice flow -- if you get my meaning...

One thing though:

The last check box on the Stitcher tab allows one to select
Soft Blending(...,only TIFF output)

Could you enable that for JPEG also? I have different workflows
(listen to me talk like a big time panographer - heh). Sometimes
it's convienient to work in JPEG. With out Soft Blending, I can
get really hard seams that are quite visible and difficult to
blur and hide in post.

So could you enable soft blending in JPEG also?

Yes this has already been added for the next release of
hugin/enblend.

Oh thank you!!!

[Daniel M German]

I am curious, is anybody using any of the tools below? Should they be
still maintained?

PTblender

PTcrop and PTuncrop

PTmasker (implements Rik's method to blend different depth-of-field
images, and computes alpha channels for masking)

PTmender

PTroller

PTtiff2psd (only 8 bit support due to lack of documentation on 16 bit
PSD files)

Yes, to color correct single images (Nadir shots at different
exposure). Works way better than PTGui or hugin exposure correction
(because it's non-linear.)

I must admit that I didn't test the other tools, but since they are
command line (and I'm a fan of windows batch files ;-) I'd not drop
them.

I thought about adding a makefile target for PSD + enblend output using
tiff2psd sometime. But I remember that some people had problems with it.

It shouldn't be hard to extend the Hugin makefiles to support all these
tools, but since this currently means that vignetting and exposure
compensation and HDR stitching won't be working, it is not of a very high
priority for me, even if PTmender has some other nice features.

I'd very much like a tool that could simply insert or delete the
crop offsets in a TIFF - Ideally without rewriting the whole file.

This would be useful for creating an SVG layer from a cropped TIFF
or adding offsets to an image fragment.

libtiff contains a utility program (tiffset, if I remember correctly) that
allows setting tiff tags. This can be used to set XResolution, YResolution,
XPosition, YPosition tags.

Hi Pablo,

I would not worry about creating Makefile support for panotools
utilities. let the power users do it their own way. I feel that the
command line tools are there for those who want to use them, but you
should not make hugin more complex than necessary to be able to
support.

Of course, this is only my opinion.

hi Bruno,

If the file does not contain the TIFF entry for this info, then the
file has to be rewritten (the new TIFF header changes the offset of
the beginning of the data).

PTcrop and PTuncrop do not alter the any of the pixels that fall
within the crop data (PTcrop will remove them).
