Hello All,
A couple of days ago i had installed a GNURadio digital image
processing block that makes an image source and sink block available as
displayed in the image below.
*Resource* : https://github.com/a-w-s/GNURadio-DIP
*Flowgraph* : http://i.imgur.com/1lJzD.png
The output of the image source and the input to the image sink are "floats"
only and nothing else. I tried to collect pixel information into a file
sink and i am successful at that but the problem comes in when the size of
the input file size is not the same as the size of the file sink output.
The image is a basic black and white test image called lena.bmp whose file
size is 65.0 KB. The link to which is also provided below ,
*Resource to Image :*

The file size of the received file (file sink) is 76.0 KB.
The reason why I pay more attention to this is because i intend to
calculate BER / Pixel Error Rate which would take into account a reference
stream which in this case would be the file with the extra bits , and Image
sink output ( or the demodulated output) .
Please feel free to ask me any questions that one might have .
Thanks and regards,
Josh.
