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 about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
