Introduction

• Why Intelligent Surveillance System?
• There are lots of CCTV cameras and digital video
  recorders at airports, stations, banks, companies
  and so on for security, surveillance, and crime
  prevention.
• Current surveillance system needs many operators
  and it takes so long to review the video that has
  been recorded.
• Intelligent Surveillance System is based on
  Computer Vision so that computer can
  automatically analysis the video information
  which acquire from cameras.
• Master-Slave Camera System
• High resolution images are needed for further
  perceptual analysis like face recognition,
  activity recognition and audio-visual speech
  recognition
• Master Camera is a static camera that has a wide,
  fixed field of view.
• Slave Camera is a dynamic camera that pan, tilt
  and zoom so that acquire high resolution images.

What I have done

• Get the movie from SNC-RZ25N camera using Sony
  Network Camera SDK.

5
What I have done

• Segment the foreground pixels of the images using
  a MoG (Mixture of Gaussians).

6
What I have done

• Group the foreground pixels into components based
  on pixel connectivity by a connected components
  algorithm.

Future Work

• Calculate the correspondence relation between the
  view of master camera and slave camera
• Transform the coordinates of object in the view
  of master camera to that in the view of slave
  camera
• Control slave camera so that acquire high
  resolution image of objects
