Master-Slave Robots ( electronics, (embedded software?)) How can two robots be made to run in parallel at the same distance, at the same speed? Master robot moved manually, control the slave (1) Master has laser, slave has specially designed complex sensor (2) Master has LEDs, slave has camera Possibly microcontroller system and interface to sensor/electronics MasterSlave

Master – Slave (1) Laser

Master – Slave (2) Black White 64us Horizontal sync pulse 5us Position of pulse gives relative position of vehicles

Robot Vision, Frame-grabber (electronics) data / address multiplexer (probably FPGA or CPLD) uC/uP fairly powerful, fast, low power software read_ and_process image data Camera uC Memory Address generator small mobile robot

Incident Capture (Software C++) Software project C/C++ on PC Rotating image- frame buffer (in RAM) process image (in parallel) When event occurs re-direct storage Event is captured, and saved to hard disk Now needs more serious image processing process image storage control

Signature analysis ( Matlab simulation) Generate database of 20x5 signatures Identify tools, parameters etc. to allow human signatures to be distinguished –perhaps Fourier analysis, wavelets, principal components (angle, slope etc.) –How many groups of letters? –How close together are the letters? Identify signatures, confidence measure

Detection of Tampered Images (Matlab simulation) Digital Images are often not allowed as evidence in a courtroom. Can a computer detect that an image has been changed when the human eye cannot? Database of images, tampered and original Various analysis methods, Image statistics
