I am doing a project implementing the physical security for FPGA based system and I am implementing a Optical PUF(physicaly unclonable function) which uses image of a authentication token and convert it to the bit stream and save it on FPGA. But I am not able to figure out how an Image is converted to the bit stream. Some one told me of a gabor filter but it just detect the edge but does not convert it to bit stream. .
Paper from where I am trying to implement PUF is attached.

Bitstream contains the implementation data of all the logic which goes into the FPGA. Probably you can create a image information and store it in BRAM's inside the information. Hope you know the contents of the bitstream for an FPGA.

Hi athandr ,
I want to save my image in RAM, or is that from image block is enough ?? I mean it is automaticly saved in RAM?
how can I use look up table in simulink? I mean read the coefficnts and image form . mat file and coonect it to look up table?
MY coeffints which are about 1 miliion in one case are constant for esch block, so I think I need to use look up table.
how can I impleemnt it?
