Representation of VEC-format Information in Color-Based Format

This web-service performs a conversion of the VEC-format used in previous GREC Arc Segmentation Contests to the Color-Based Segmentatation Evaluation as used in the GREC 2007 Arc Segmentation Contest and described in the paper Pixel-Accurate Representation and Evaluation of Page Segmentation in Document Images (ICPR 2006). If you have any questions, please contact Faisal Shafait.

Note that the representation in the image file is what counts for the evaluation. In some test cases we noted that the VEC-format representation can be inaccurate. You might want to consider post-processing the resulting image file if you use this web-service for conversion.

Note also that this conversion only accepts lines starting with A or C (arcs and cirlces) and will fail if there are lines or comments in the VEC-format input.

Form Interface

You need to upload the original binary image and a VEC-format text file. We recommend you upload a png image file. (Other formats work, but may be too large or lossy.)

File1 = Orignial Binary Image (max. 2MB):

File2 = VEC-format Text File (max. 2MB):

Programmatic Interface

To submit your image programmatically, you can simply POST to this URL; the input should be parameters named "imagefile" and "vecfile".

From the command line, you can do this using: 

curl -D header.out -F 'imagefile=@input.png;type=image/png' -F 'vecfile=@vecfile.txt;type=text/plain' http://demo.iupr.org/vec2img/ > output.txt

You can also do this easily using the HTTP implementation in your favorite programming language (C#, Python, Java, Perl, etc.).
