<p class="MsoNormal"><span style="font-size:14.0pt;line-height:115%"></span><span style="font-size:12.0pt;line-height:115%">The digiKam photo management program
allows users to manage their photo collection and apply certain changes to
image properties. It is quite common that the user deals with maps of different
regions and also the map search tool. An interesting application that can be
developed in the digiKam environment is to automatically tag the various
parameters on the image. These parameters, like street, country, town etc. can
be predefined by the user, and they will automatically be tagged by using <i>reverse geocoding</i>. For this work I plan
to develop backends to ‘<a href="http://geonames.org" target="_blank">geonames.org</a>’ and ‘Google maps’ to fetch the string of
the relevant lat/long pair and manipulate the image accordingly so as to tag
it. This project also aims at modifying the map search in digiKam to allow users
to predefine the number of images and then display them on the map. </span></p>

<p class="MsoNormal" style="line-height:normal"><b><i><span style="font-size:14.0pt">Benefits
to the community:</span></i></b></p>
<p class="MsoNormal"><span style="font-size:12.0pt;line-height:115%">The recently
developed digiKam map search is able to make a search based on a rectangle area
defined by the GPS positions. Development of this project will create a user
interface for end users, where the software will automatically tag predefined
parameters on the map, a task which is generally time consuming and tedious.
Also, the map search can be complimented with the display of predefined number
of images on the map pertaining to the region of interest. This particular feature
along with the recently developed kde education project ‘Marble’ will add a new
dimension to map search technology from the user perspective. The further
integration of the two can enable a location search where the user given
location map is displayed, with a predefined number of images, predefined
number of tags on that image, and the ‘Marble’ widget enabling its own class of
features. </span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;line-height:115%"> </span></p>
<p class="MsoNormal" style="line-height:normal"><b><i><span style="font-size:14.0pt">Necessary
work to be done:</span></i></b></p>
<p style="line-height:normal"><span style="font-size:12.0pt"><span>1.<span style="font:7.0pt "Times New Roman""> </span></span></span><i><u><span style="font-size:12.0pt">XML schema:</span></u></i><span style="font-size:12.0pt"> In my earlier work I had thought that a new XML
schema needs to be designed for this purpose. However after interacting with
one of the digiKam developers, I now understand that digiKam already has a
tagging system and it will be a lot easier to integrate the work with this
system. DigiKam stores these tags in the XMP and IPTC areas of the picture.
Hence there is no direct need to develop a new XML schema.</span></p>
<p style="line-height:normal"><span style="font-size:12.0pt"><span>2.<span style="font:7.0pt "Times New Roman"">
</span></span></span><i><u><span style="font-size:12.0pt">Implement Backends:</span></u></i><span style="font-size:12.0pt"> Once the user specifies the parameters that are to be
tagged on the image, the automatic tagging needs to be implemented. This
process will require JavaScript development. The backend application will need
to be developed that will fetch the relevant information. The information like
name of street etc. will be retrieved in this process.</span></p>
<p style="line-height:normal"><span style="font-size:12.0pt"><span>3.<span style="font:7.0pt "Times New Roman"">
</span></span></span><i><u><span style="font-size:12.0pt">Implementing the tagging:</span></u></i><span style="font-size:12.0pt"> Once the requisite data is retrieved from
<a href="http://geonames.org" target="_blank">geonames.org</a> and google maps, it will be stored in program memory. The digiKam image
manipulation plugins like text writing and drawing squares etc. now need to be
implemented. In this procedure, the tag names will be written onto the image. <b>Variable colours may be implemented for
tagging different parameters.</b></span></p>
<p style="line-height:normal"><span style="font-size:12.0pt"><span>4.<span style="font:7.0pt "Times New Roman"">
</span></span></span><i><u><span style="font-size:12.0pt">Displaying pictures on the map:</span></u></i><span style="font-size:12.0pt"> This is a crucial step in the project. The map search
keyword stored earlier now comes in the picture. Also, as suggested by Mr.
Michael Hansen from the digiKam community, the tag names given to the image can
directly be used for the picture search. The database will be searched for
pictures pertaining to these keywords and the select number of pictures will be
displayed on the map.</span></p>
<p style="line-height:normal"><span style="font-size:12.0pt"><span>5.<span style="font:7.0pt "Times New Roman""> </span></span></span><i><u><span style="font-size:12.0pt">Selective display:
</span></u></i><span style="font-size:12.0pt">An interesting feature that may
be implemented is of selective display of images. It will involve taking
information from the user as to the domain of search. For example sports. And
then search only this domain for the pictures !!</span></p>
<p class="MsoNormal" style="line-height:normal"><span style="font-size:12.0pt">The
last part of the necessary work will make the project more complex. Hence I
plan to implement it only if time permits.</span></p>
