Simulink Blocks for Video Surveillance

Configuring the sad blocks

  1. Configure one of the “Add” block for subtraction, you may also change its icon shape to a circular form as follows The symbol “|” is used to place the “+” and “-“ perpendicular to each other :
  2. Configure its fixed point mode of operation Configure one of the “Matrix Sum” blocks for adding rows:
  3. Configure its fixed point mode of operation
  4. Configure the fixed point mode of operation for the second Matrix “Column Add” block:

Configuring the input blocks

  1. Configure on of the “Video Source” "From Multimedia File" block for reading frames from the "vipmen.avi" file.
  2. Set the initial value of the "Constant" to 1e5.
  3. Configure "Data Type Conversion" block :
  4. Configure " Relational Operator " block :
  5. Configure one of the " Matrix Concatenate " block :
  6. The “Floating Scope” will be used to display the motion energy and the threshold The threshold is changed upon a user command. The simultaneous display of the threshold and motion energy will enable the user to follow-up the process of recording frames. as a function of time. Double-Click the block. A cope screen will appear, you should then click the icon as shown in the following picture:
    You may keep the default configuration for "Data history".
  7. Configure the " Insert Text " block :
  8. Double-click on the "Enabled Subsystem" block, and build it as shown below:
  9. Double-click on one of the "Subsystem" block and build it as shown below:
    Save the subsystem as: "Motion Energy"
  10. Double-click on one the remaining "Subsystem" block,build it as shown below and name it "Frame Counter":

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
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.
what is the actual application of fullerenes nowadays?
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.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
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.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
