Multi-hop, Wireless Flooding SimulationType: Java Applet 8.8 kb Description: Flooding is another technique inspired by nature and used in sensor networks to spread information. When a node receives a message it simply broadcasts it on the radio channel to all its neighbours. Communication in sensor networks is difficult because radio signals transmitted by one node can interfere with those of another. You can see this in the flooding simulations as yellow dots (corrupted signal) amongst the blue dots (clear signal). 429 views since 28-06-2007 |
Synthetic dynamic hologramType: Apple Quicktime 31.0 Mb Description: 1500 frames that are encoded with laser onto film in order to create a synthetic dynamic hologram.

Cube graphSupervisor: Jamie Simpson (Curtin) Type: Remote site Description: Graphs are useful in many circumstances, e.g. for representing a network of computers and links between the computers without the need for humans to spend time putting it together. In this applet, the points are connected by edges as of a cube, however the points start at random locations. The cube forms as short edges try to expand and long edges try to shrink. 444 views since 18-06-2007 |
Randnoswitch GraphSupervisor: Jamie Simpson (Curtin) Type: Remote site Description: Graphs are useful in many circumstances, e.g. for representing a network of computers and links between the computers without the need for humans to spend time putting it together. In this applet each time you load the page, different points will be connected. The points begin at a random location, but you will see the diagram unfold and form an orderly structure, as the points repel but the lines hold the connected points close. 348 views since 18-06-2007 |
Petersen GraphSupervisor: Jamie Simpson (Curtin) Type: Remote site Description: This graph is one of the graphs most commonly used by mathematicians as an example of various properties. This program finds ways of displaying the graph by placing the points at random locations and refining the graph by pushing points away from each other and pulling connected points closer together. The Wikipedia article describes a Petersen Graph 413 views since 18-06-2007 |

Onetwenty is a group of PhD students mainly from UWA, and many were part of the 60hz real-time graphics research group. It was developed in linux with their own custom physics, animation and rendering systems, along with other libraries such as OpenGL, SDL and fmod(for sound) 1666 views since 12-04-2007 |
Detection of FingerprintsSupervisor: Dr Peter Kovesi Type: Animated GIF 3.6 Mb Description: Fingerprints are made up of ridge lines and intervening valleys. The points at which these lines branch or terminate are the features used in fingerprint based identification. In this image, the fingerprint itself is separated out from the rest of the image by identifying where the ridge pattern is more or less uniform over a small area of the image. The ridges are then enhanced using a process that smoothes, or blurs, the image along the direction of the ridges, but not at right angles to the ridges. Watch carefully as small breaks, false joins and zigzags are gradually removed from the ridge pattern. 823 views since 12-04-2007 |

Corridors of Disease SpreadSupervisor: Professor George Milne Type: image/gif 126.4 kb Description: This simulation reproduces a real life landscape with imaginary towns and transport links between them. Towns and roads are human influenced and attract high population densities. Natural features such as rivers lead to development along their shores. Conversely, other geographical features such as mountain ranges or swamps will limit development. 1150 views since 07-07-2006 |
Barriers to Disease SpreadSupervisor: Professor George Milne Type: image/gif 82.5 kb Description: The simulation shows how a model can simulate the effects of erecting barriers to slow or stop virus spread. As seen in the foot and mouth disease epidemic in Great Britain during 2001, a key to slowing down disease spread is restricting movement. Other measures included the culling of livestock or the inoculation of livestock. 1500 views since 07-07-2006 |

Face detection with template matchingSupervisor: Assoc Prof Mohammed Bennamoun Type: Windows AVI 7.2 Mb Description: Before we can do face recognition, the portion of the image that contains the face must be first detected. Here is a demo on face detection using template matching. A frontal face template was used to detect the presence of a face in each frame of the video. We see that although the algorithm did not manage to detect the face when the subject turned his face side-way or tilted his head by a significant amount, as soon as the camera captured the frontal view of his face, the rectangle immediately locked onto his face again. 1717 views since 30-06-2006 |

3D ReconstructionSupervisor: Assoc Prof Mohammed Bennamoun Type: video/x-msvideo 3.5 Mb Description: Using a structured light system, we can reconstruct the complete 3D models of any objects and put them into a database. When an image of any of these objects is taken at a later time, we will have no problem in recognizing them. The video here shows the recognition process of several objects with some significant occlusion -- for instance, the bottom of the toy chef is not visible in the image; the tail of the toy dinosaur is missing -- yet all the objects were recognized successfully. Not only so, from the 3D models stored in the database, the missing parts of the objects can all be filled in. 760 views since 30-06-2006 |
