PPT-Edge detection

Goal Identify sudden changes discontinuities in an image Intuitively most semantic and shape information from the image can be encoded in the edges More compact than pixels Ideal artists line drawing but artist is also using objectlevel knowledge. ABQ Leak Locator brings years of systems engineering and in-depth technical problem solving methodology to the table to apply toward benefiting its clients and customers. I wrote it because at the time I was concerned that the potential bene ts of dashboards were being undermined by a great deal of confusion about what a dashboard was The term dashboard needed a clear de nition In the article I proposed a working de we have evolved the process and methodology of leak detection and location into a science and can quickly and accurately locate leaks in homes, office buildings, swimming pools and space, as well as under streets and sidewalks, driveways, asphalt parking lots and even golf courses. 02nT Faster cycle rates Up to 10Hz Longer range detection Pros brPage 5br Magnetometers Magnetometers Large distant targets mask small local targets Difficult to pick out small target due to background noise No sense of direction of target on single Fast Edge Detection.
