KHW0801Multi-camera vision alert system for the
Government Flying Service search and rescue
missions (CS/CE)

• Multi-camera vision alert system for the
  Government Flying Service search and rescue
  missions (CS/CE)
• We will develop a Multi-camera vision alert
  system to assist the aircrew and pilot on rescue
  missions carried out by the Government Flying
  Service GFS (http//www.gfs.gov.hk/). The system
  will use images from onboard cameras to identify
  shipwreck victims and alert users when possible
  objects are identified. We will use multiple
  cameras to enhance the tracking compatibility,
  that is, each camera is responsible for a small
  portion of the search area. The work also
  include
• Identify possible search objects using color and
  other information.
• Record data during the whole search mission for
  later retrieval.
• Students may be required to participate in test
  flights during installation and development.

KHW0802Mobile handheld projector (CS/CE)

• Handheld projectors are now available in the
  market. However, in many situations, the
  projector is not projecting perpendicular to the
  screen therefore the image may be distorted.
  Using the camera on the mobile device, we can use
  computer vision methods to correct this
  distortion. It may even be possible to reduce the
  vibration created by an unsteady hand. There
  should be many cool applications based on this
  system. Similar project

KHW0803Interactive spoken language tutorial
system (CS/CE)

• The target is to develop an interactive system
  that can tell whether a student is speaking a
  language (e.g. English or Mandarin) with the
  correct intonation. The system first analyses the
  recorded sound and calculates the pitch profile.
  Then it compares with the standard answer and
  shows using graphics or audio feedback to
  instruct the user for further improvement.
  Students of this project have to learn
  mathematical techniques of signal processing of
  speech first. The work include data collection,
  programming and building user interfaces.

KHW0804 A 3-D volumetric display system (CE)

• The aim of this project is to develop a system to
  display 3D models that are viewed by naked eyes
  without the use of any visual tools such as
  shutter glasses. The method uses a rotating (or
  vibrating mirror) with a holographic diffuser (to
  limit the viewing angle, ie. on screens of ATM
  machines) to reflect images from a monitor to the
  user. As a result each eye can see a different
  image so a stereo effect can be formed. The work
  include 1) control a rotating/vibrating mirror.
  2) develop the driver for a graphic card to
  display images synchronous with the mirror
  position. This is a challenging project with high
  commercial potential.

KHW0805Large flexible LED display wall (CE)

• We propose a new distributed and easy deployable
  (LED based) display technology for large
  irregular shape objects (external or internal
  walls of buildings). For example, we can show an
  MTV video on the surface of a large (100 meters)
  Christmas tree using 1 million LEDs. It is
  different from the current matrix display. In our
  system each LED is serially linked and is free to
  be placed in any position. After the LED
  positions are fixed, we can use a video camera to
  obtain these positions and use computer
  graphics/vision technology to map them to the
  video pixels. The work include (1) using VHDL and
  Xilinx to build the hardware module for each LED.
  (2) Computer graphics/vision research work for
  locating the LED positions and calculate the
  corresponding mapping. Build software for
  handling/editing the video for the artistic
  designer. This displaying technology will give a
  new perspective to the advertising industry.
