[digiKam-users] Extracting thumbnails

Wesley Smith
I have managed to lose an entire collection of images spanning years.  I've tried every way to get them back but, they are gone.  I can still see all of the thumbnails and so I know I can somehow extract them but, I don't know how.  It's the only thing I have left of them. I know they're small but, that's better than gone.
I have tried opening the database in sqlite browser and extracting, I've tried a python script that was hopeful but, the files exported are not images, just *.blob.  
What can I do?

Hi,

blog are images in fact in wavelets compression format PGF :

The actual blob is first of all a QByteArray compressed with qCompress.

Re: Extracting thumbnails

Wesley Smith
Ok. So that is a little beyond my knowledge base. Is there a way, having exported the blobs, to decompress them?

Hi,

I prepared a small set of codes to load compressed blob file from
database and convert to png.

It's on my github account here:

https://github.com/cgilles/digikam-pgf-database

To compile, you need Qt5 devel package (core and gui) and cmake :

git clone https://github.com/cgilles/digikam-pgf-database.git
cd digikam-pgf-database
mkdir build
cd build
cmake ..
make

enjoy...

Re: Extracting thumbnails

I hate not being able to figure this out but, I have an issue.  I'm not at all familiar with QT.  I'm using Windows 10 (latest stable build) and I just installed cmake and Qt.  I followed the instructions but, cmake is not able to find some things.  Here is the output:

Looks like missing Qt5_DIR.  I don't know how to resolve.

How did you get this trace ? From a windows terminal with MSVC setup ?

Did you install Qtcreator ? I need to know more details about the
install from your system.

Hi,

I just add a bootstrap.bat script for Windows. Take a look, you can
customize the Qt5_DIR variable, which is the root install path to Qt5.

Re: Extracting thumbnails

Thank you for that.  I did run it and ran into some issues.  I then ran a command prompt from within Visual Studio Community edition 2019 and tried again.  Here is the output.  It is looking for a path I'm not familiar with.

Re: Extracting thumbnails

Gilles Caulier-4
In fact i know well the error, as i devel with Qt in my office under
Windows and MSVC.

You need to launch the MSVC terminal, not the standard Windows
terminal (aka "cmd").

This MSVC terminal init a lots of variables to be able to use the CLI
compiler from Microsoft (i hope that you install the CLI MSVC tools
with the Mircost compiler installer).

You will found the MSVC terminal in Run Windows menu, MSVC section,
and advanced tools (or something like that). There are many version,
to cross compile to ARM or in 32bits. for get these ones, and take the
native 64 bits version.

Voilà.

Re: Extracting thumbnails

Would this be a result of using VS Community 2019?  I've launched the prompt from VS and still get the same errors.

Windows and MSVC.

You need to launch the MSVC terminal, not the standard Windows
terminal (aka "cmd").

This MSVC terminal init a lots of variables to be able to use the CLI
compiler from Microsoft (i hope that you install the CLI MSVC tools
with the Mircost compiler installer).

You will found the MSVC terminal in Run Windows menu, MSVC section,
and advanced tools (or something like that). There are many version,
to cross compile to ARM or in 32bits. for get these ones, and take the
native 64 bits version.

Voilà.

[digiKam-users] Face recognition

Ronald Orenstein
In reply to this post by Wesley Smith
I have had some excellent online help from a list member in response to my last post, but I wanted to bring my further query to the wider list and the developers.

I was running v. 6.4 for mac, and had used it to tag a large number of faces, many of which I identified manually.  Following advice, I updated to version 7.0 for mac, which I realize uses a different algorithm for face recognition.  As I did not want to have to retag hundreds of images, I did not delete tags made under the earlier version, but rescanned a few folders with the setting on 'scan again and merge results' and 'recognize faces'.  The new scan, however, placed all newly-scanned files under 'unknown'.  I retagged a large number of faces, mostly showing my wife, and tried a further scan on the same settings (but using the scan command under tools>maintenance) expecting that it might now learn from these newly-tagged files and recognize the faces of my wife at least. 

Unfortunately, the program crashed before completing the scan, but not before adding a few thousand new faces.  However, once again almost all of these, including my wife's face, were placed under 'unknown' rather than being recognized; the few placed under 'unconfirmed' were wrongly identified.  Rescanning individual files had no effect.  This makes me wonder if the recognition feature is working (or if I am doing something wrong).

Further, under both 6,4 and 7.0 the scan is failing to detect many faces in photos with more than one person even though these are (as far as I can tell) every bit as large and clearly visible as the ones it does detect.  I tried rescanning the same files repeatedly with different sensitivity settings, from 0-100%, but the results were always the same.  Is there anything I can do about this short of manually adding faces to thousands of files?

Thanks for assisting me with this.

Re: Extracting thumbnails

I've tried all of the shortcuts for msvc and they all give me a similar result.  Not sure what to do.  It's frustrating being so close but, unable to obtain the goal.

This is strange.  It sound like your don't use the right MSVC terminal
which set the PATH to compiler.

You don't need to play with build dir. bootstrap script will do it for you.

Program is here :

Re: Extracting thumbnails

Gilles Caulier-4
Wesley,

Did you seen my last message ? You have now a Windows executable ready
to use "as well" for your problem. I would to receive a feedback
about.

Also can your share me some database thumbnail blobs to test here,
just to be sure that all will work as expected ?

Thanks in advance
