Extract a motion filter using camera movement in number of pixel and angle, in VHDL or Verilog
Implementing that function in Verilog or VHDL is far from trivial. 
Also what I gather this has to be calculated for each pixel. Thus it will need a s[censored]od amount if pipelining and/or parallel processing. 

Then you still need a way of getting the pixels into and out of your FPGA. 
All and all a project which, I won't say can't be done, but I very much suspect is beyond your abilities.
