2. Project Proposal  Develop a system that can detect and highlight a moving object  Applications:  Security camera  Traffic flow control  Presence detector  Safety – e.g. Swimming pool

3. Overall System Camera Processing System Video Display Controller

4. Functional Block Diagram Camera Noise Filter, Gray Scaling RS-232 Processor Memory User Controller Video Display Movement Filter, Resolution Control

5. Camera A low resolution Polaroid Digital 320 will be used to periodically send serial data to the processor Camera Specifications: Resolution: 320 x 240 Power: 9V DC Supply Interface: RS-232 serial

6. Noise Filter and Gray scaling  Grayscale camera image to reduce image size  Reduce processing time  Remove noise from video signal in non- ideal lighting conditions  Reduce false movement

7. Processor  The Motorola 68000  Features include:  Assembly Language  8MHz, wire-wrapping  24-bit memory addressing  16-bit bus

8. Memory  Processor will send each frame to memory  Two megabytes of memory will be used  If more is needed a second processor will be connected in parallel to expand the memory to four megabytes

9. Software  The software will take in a frame and the previous one  The two frames will be subtracted from each other, and moving objects will be detected  If a moving object is detected the object will be highlighted in the image

10. Controller  User interface:  9-button keypad  Adjustable resolution of picture  Temporal and spatial filtering can be controlled to remove unwanted noise  e.g. Rain and movement of tree leaves

11. Movement Filter  The processor will compare each frame with the previous frame to detect motion  If motion is detected the processor will be programmed to highlight the moving object  Output frame with moving object highlighted

12. Video Display  Processor displays image on a computer monitor  NTSC  Specify frames per second  Specify number of pixels

13. Power Supply  Design and build an power to supply to take 120VAC to 3.3VDC, 5VDC, and 9 VDC

14. Functional Example

15. Safety  Shield user from all potentially harmful voltages  No moving parts

16. Risks and Contingency Plan  Allocate enough time for unfamiliar components  Not familiar in video display technology  Speed of identifying algorithm  Try multiple approaches until desired time is acceptable
