Connecting the blocks:

  1. Connect the blocks as shown in the following figure:
    Video Surveillance model
  2. Save the model as "surveillance_sim.mdl".

Running the model

  1. Run the model. You should observe the following images:
    Current Frame Recorded Frame
  2. Double click the scope and you will see:
    In this scope display, yellow represents the motion estimate from each video frame, and magenta is the threshold level. In the Motion Threshold scope here, we see that we identified five frames with motion above the threshold that were captured and recorded.

Real time implementation

Video surveillance using tcp/ip

  1. Open the “ video_sim.mdl ” Simulink model (generated in the " A Framework for Video Processing with the DM6437 DVDP " module).
  2. Rename the model "my_dm6437evmsurveil_tcpip.mdl".
  3. Rename the “R_W Algorithm” subsystem to “Surveillance Algorithm”.

  5. In this block, add a Add the “Function- Call Subsystem” from the “Ports&Subsystems" group of the "Simulink" Blockset.
  6. Rename “Function- Call Subsystem” to “Video Frame Capture Motion Threshold” and Double-click it.
  7. Open the model "surveillance_sim.mdl", created in section and copy it into “Video Frame Capture Motion Threshold ”.
  8. Add three input ports "In1" from the "Sources" group of the "Simulink" blockset and three output ports "Out1" from the "Sinks" group of the "Simulink" blockset.
  9. Add a "Switch" from the "Signal Routing" group of the "Simulink" blockset and a "Gain" from the "Math Operation" group of the "Simulink" blockset.

  13. Configure the "Switch" block :
  14. Double-click the “Surveillance Algorithm” subsystem.
  15. Configure the "Byte Unpack" block :
  16. Configure the "Byte Pack" block :
  17. Configure the " TCP/IP Receive " block :
  18. Configure the " TCP/IP Send " block :
  19. Connect the “Video Frame Capture Motion Threshold ” block as shown:
  20. Open the “RW_pcl_tcpip.mdl” model, created in the "Video R_W" file
  21. Rename the model "my_pc_surveil_tcpip.mdl".
  22. Add the "Manual Switch" from the "Signal Routing" group of the "Simulink" blockset and three "Constant" blocks from the "Signal Processing" group of the "Signal Processing" blockset.
  23. Configure the " Constant " blocks:
  24. Configure the "Byte Unpack" block :
  25. Connect the block as shown:
  26. Configure the " TCP/IP Receive " block :
  27. Double-click the “Display” subsystem.
  28. Double-click the “Data Unpack” subsystem.
  29. Configure the "Byte Unpack" block :
  30. Connect the block as shown:
  31. Add to the "Display" subsystem the "Insert Text" from the " Text&figure__" group of the " Video and Image Processing " blockset, " Floating Scope" from the "Sinks" group of the "Simulink" blockset.
  32. Configure the " Insert Text " block :
  33. Add the “Subsystem” from the “Ports&Subsystems" group of the "Simulink" Blockset
  34. Rename it "Combine Count"
  35. Add a "Frame Counter" subsystem as we did in paragraph 14 at the first section.
  36. Add a "Matrix Concatenate" from the "Math Operations" group of the "Simulink" blockset.
  37. Connect the block as shown:
  38. Configure the " Matrix Concatenate" block :
  39. Connect the "Display" subsystem as shown:
  40. Open a new m-file, copy the following code and save it as "my_tcpip_surveil_script.m" at the same directory as the model. function my_tcpip_surveil_script(hostModelName) %my_tcpip_surveil_script controls host-side TCP/IP processing for% Video Surveillance demo: % 1) Builds and runs the target application%********** Initialization ******************** % Get model namemodelName = gcs;% Connect to CCS CCS_Obj = connectToCCS(modelName);saved_visibility = CCS_Obj.isvisible; CCS_Obj.visible(1);% Load applicationloadApp(modelName, CCS_Obj);% Run application fprintf('Running application: %s\n', modelName);CCS_Obj.run;% Allow some time for DHCP address acquisition pause(3);% Retrieve target's host nameboardType = get_param([modelName '/IP Config'], 'boardType');userPrompt = sprintf('Enter the IP address or the host name of the %s board: ', boardType); hostName = inputdlg(userPrompt, 'Target IP address');if isempty(hostName) errordlg('You have to provide a valid IP address or host name to run the demo.', ...'TCP/IP Surveillance Recording', 'modal'); return;end hostName = strtrim(hostName{1});% Launch host side UDP receive / Video display model fprintf('Launching host side application: %s\n', hostModelName);open_system(hostModelName);% Update host side TCP/IP blocks with target's IP address set_param([hostModelName '/TCP//IP Send'], 'Host', hostName); set_param([hostModelName '/TCP//IP Receive'], 'Host', hostName); fprintf('Click on play button to start running the host side application!\n\n')%[EOF]tcpip_surveil_script.m
  41. Open a new m-file, copy the following code and save it as "my_tcpip_surveil_script.m" at the same directory as the model.
  42. now we have two models ("my_pc_surveil_tcpip.mdl" and "my_dm6437evmsurveil_tcpip.mdl") and one MATLAB file ("my_tcpip_surveil_script.m")

Running the real-time model

  1. Build load and run the project from the "my_dm6437evmsurveil_tcpip.mdl" model. Double-click the " Build / Reload&Run" block.
  2. Running the script, you will see:
    If you want to display the Absolute Differences Image, change the state of the switch from 0 to 1. You will then see:

are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
