License plate reader

The iso image below contains a live CD with a real time license plate reader optimized for Czech Republic and Brazil. You do not need to install anything, just burn the CD and reboot your computer with disk inside.

The CD contains also some images of plates and cars that you can print and use for your tests.

People counter

The iso image below contains a live CD with a real time people counter. The counter is easily configurable to work for top or for lateral view and lets you select a minimum and maximum size so that the counter would count only targets with a specified size.

The counter works with live streams as well as with pre-recorded videos being the offline mode more precise because more CPU time could be allocated to the algorithm without affecting the frame rate.

To reduce to the minimum the errors the counter runs 45 instances of itself with different parameters and a higher level piece of code analyzes the result of all them to give the right count. You can see the result of each instance on the bottom right window as a colored bar and the output of the overall counter immediately below it.

The best results are obtained when the images are processed at a constant 30 fps, but this is not always possible on live stream because each extra instance of the counter lowers the frame rate.

The live demo has been developed considering a fast CPU and this is the reason why 45 instances of the counter are running contemporaneously. If you see that the counter does not behave as you expect is because the fps dropped below a certain value making the system less precise; in this case enter in contact with me that I'll make another demo with less CPU usage.

You do not need to install anything, just burn the CD and reboot your computer with disk inside.
