    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).

  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:

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments

not now but maybe in future only AgNP maybe any other nanomaterials

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
