I am performing OCR (optical character recognition) on a bunch of images. Images are grouped into different projects (tickets, credit cards, insurance cards etc). Each image represents an actual product (for instance, if we have images of credit cards, picture1.jpg is image of my credit card, picture2.jpg is image of your credit card,... you get it).
I have a settings.
xml file, which contains regions of the image, where OCR should be performed. Example:
<Project Name="Ticket1" TemplateImage="...somePath/templateTicket1.jpg">
<Region Name="Prefix" NumericOnly="false" Rotate="0">
<x>470</x>
<y>395</y>
<width>31</width>
<height>36</height>
</Region>
<Region Name="Num1" NumericOnly="true" Rotate="0">
<x>555</x>
<y>402</y>
<width>123</width>
<height>35</height>
</Region>
</Project>
</Project Name="CreditCard" TemplateImage="...somePath/templateCreditCard1.jpg">
<Region Name="SerialNumber" NumericOnly="false" Rotate="90">
<x>332</x>
<y>12</y>
<width>20</width>
<height>98</height>
</Project>
I would like
to set these parameters through GUI (now I just write them into
xml file). So, first I load a template image for a project (an empty credit card). Then I would like
to draw a rectangle around a text, where OCR should be performed. I guess this isn't hard, but it would be great if I could also move and resize this rectangle object in the picture.
I have
to display all regions (rectangles) on the picture also. Also - there will probably be a list of regions in a listview, so when you click a region in this listview, it should mark it on the picture in a green color for example. Do you know for a library, which I could use? Or a link with some tips how
to create such objects?
