This software app is open source.

This means I was not able to invest a lot of time and money into buying and testing different systems/platforms etc.

The advantage of open source being completely free and open (as compared to commercial software, freeware or shareware) is usually not always completely free -
|

the user may help the developers by sending them errors or improvement suggestions.

Lastly, a note: please respect the GPL: If you use (parts of) this software in your own project, publish the complete source code of your own project, as well.

I developed this software app for different platforms (e.g. Windows, Ubuntu, Fedora).

<span class="emphasis"><em>Scanned Image Extractor</em></span> is a tool for efficiently extracting rectangular photographs from album or (multiple) photograph scans. It is semi-automated, hence it tries to suggest recognized photographs but you have to verify, delete bad suggestions and possibly add missing photographs manually.

If you use version 2 of OpenCV, then you will need to add "-DOPENCV2=1" to the cmake command line.

|
||
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>
|
||
Scan an album page with at least 300dpi (however, especially for older photographs, 600dpi should be enough). As document type, choose picture/photograph.
|
||
The complete scanning process of all albums/album pages will cost you most of the time. So to improve the efficiency here, refer to the following notes.
|
||
Also make sure you have a look at <a class="xref" href="#tips" title="4.4. Tips and Tricks for using Scanned Image Extractor">Section 4.4, “Tips and Tricks for using <span class="emphasis"><em>Scanned Image Extractor</em></span>”</a>.
|
||
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
|
||
Do not use the preview system of the scanner, it will only cost a lot of time. Just scan the complete scanning area. Only use it to get used to how the result looks like
|

</p></div><p>
|
||
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
|
||
Do test your process before you start scanning all of your albums (i.e. follow this guide for some 2-3 album pages and test if everything's like you want it to be)
|
||
</p></div><p>
|
||
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
|
||
If you have good quality photographs and want to post-process the images with a 16-bit aware tool (Gimp 2.9+, Lightroom, ...), then use 16bit scanning.
|
||
</p></div><p>
|
||
</p></li><li class="listitem"><p>
|

Use <span class="emphasis"><em>Scanned Image Extractor</em></span> to extract the photographs of the scanned images (see <a class="xref" href="#howto" title="4.3. How to use Scanned Image Extractor">Section 4.3, “How to use <span class="emphasis"><em>Scanned Image Extractor</em></span>”</a>).
|

</p></li><li class="listitem"><p>
|

Organize your photographs on the file level. E.g. create folders and rename the files appropriately. Also copy comments to the filename, which people have next to their album images, quite often.
|

A tool like my <a class="ulink" href="http://dominik-ruess.de/pivot/" target="_top">pivot - photo, image and video organization tool</a> can help you here.
|
||
</p></li><li class="listitem"><p>

Organize your photographs on the (meta) data level. Add tags to your images, post-process them by adapting colors etc. Use a free open source tool like

The user interface of <span class="emphasis"><em>Scanned Image Extractor</em></span> is not very sophisticated.
|
||
It consists of three main areas, one displaying the scanned image (1),
|

one for the preview of the current photograph (2)
|
||
and lastly, one area for the extraction settings (3), most importantly for the aspect ratio (4) and orientation (5) control.
|

Start by loading a scanner image (File menu). If you want to process all, just choose the first scanned image in your directory.
|
||
Now, after some computation, the detected photographs are suggested as blue boxes in the input image.
|
||
These blue boxes will be extracted to a specified directory (see settings) as digital photograph.
|
||
When your done with the current scanned image, proceed to the next one by clicking on the respective button.
|
||
The output images of the last image will then be processed automatically, there's no need to press the "save" button every time.
|
||
</p><p xml:lang="en" lang="en">
|

Press the keys 1-9 and 0 to enforce a certain aspect ratio for the current target.

Press the keys "a", "s", "d" or "f" for fastly changing the orientation of the current target selection.

</p><p xml:lang="en" lang="en">
|
||
If you dislike the current detection(s) you can manipulate, delete or manually add them yourself.
|
||
Go to any edge or corner to change the size of the selected target.
|
||
If you press CTRL while dragging, this will be symmetric.
|
||
If you press SHIFT and then drag a corner of the selected rectangle, you can rotate it by dragging.
|
||
For adding a new selection, deselect all (click somewhere empty) and click at a corner of the photograph.
|
||
Keep the mouse pressed and drag the red line to another corner and release the mouse.
|
||
Now you have a new rectangle which you can resize by moving your mouse. Click to have a new target rectangle.

Most albums have a page format which doesn't completely fit on the scanner. Scan one page with two iterations: align the top-left page to your scanner and then turn the page upside-down and align the former bottom-right (now top-left) corner with your scanner. This will ensure - in most cases - that every photograph is contained completely in at least one of the two scans.

If you want to scan multiple single photographs (WITHOUT album), do not place them right at the scanner edge. Leave some space to the scanner boundaries and to the other photographs. This will make the automated recognition process easier and reduce the risk of the photograph overlapping the boundary when closing the lid.
|

There more space in between photographs and to the boundary, the better.
