Know your enemy

[White Rhino]

The essence of OCR is the tollerences and patterns used for recognition. These vary from engine to engine. The software has to firstly "find" your number plate in the image. So placing your numberl plate off centre will challenge the engine under load. It also has to differentiate any other letters on the vehicle from the "Number Plate" characters. There is a limit on the tollerence of angles horizontally - some software use deskew techniques to do so but are also places extra strain on the engine and costs machine time - very taxing under high volume and load conditions. Spacing between characters are also important. For eample if your's was "G  P" versus "GP" signifies two "words" versus one. The clarity of the letters - i.e. faded letters also cause strain and may fail pattern matching.

So it would be useful to find out what OCR engines are being used and see what the tolerences are and maybe there are some loopholes.

what about placing a few stickers on your card close to the number plate, using the same font and colour?

"123 fok etol gp"or something?

would that confuse the OCR engine?

In that case register a company called STP (Special Toll Plates), have decalls printed for your vehicle including 300 generic GP number plates in the standard font, colour and size and stick them on all over the car for "marketing" and start a taxi service up and down the M1/N1.
Phaak'm!

Jy wil dit nie dalk copy en paste of 'n screen grab of iets maak vir ons ouens wat nie access het nie?

Sorrie, sy woorde:
"After careful consideration - I really thought this one threw. I don't like e toll - But i have to submit to what Jesus wants me to do. If it is about the money, my trust must be in Jesus for finances.
So i'm putting my trust in Jesus and i got my e toll"

I mean really!

haai shame! en hy't sover nog net gemanage om een helkkie af te trap....  

What, can you check on the usage of other road users?
What do you need? Licence plate number?

Or did he post this image himself?

PAPI states that one should not be able to obtain another persons information from any electronic database... on the E-Toll website i can do so when typing in any registration number... ego the website/system is not PAPI complaint. Who is going to lay a charge?

Our website guys had to ensure that no one can obtain student info by just typing in a student number, you have to use ID number and passwords now. But here is a semi government website that is clearly not compliant.

Popped it on their FB page.

Sorry, I meant what is the link to the website where you can put in the registration number to see the toll fees?

[Heimer]

There is an interesting dilemma here.

To protect your personal information they need to change the website and allow you to register to access it

But forcing you to register to acces information of alleged pictures of you, allegedly using their toll gates can't be enforceable

[Sláinte Mhaith]

Found it.
But you have to click it twice. Weird.

Stand up and put your one foot back to obscure your plate.

No dilemma at all if they use the ID/Registration number combo. Then there is no need for you to register but you can check if someone has cloned your plate. Your plate number may be available to be copied while you park but your ID number should be more secure.

I was wondering why, if these cameras are so good, it would be necessary for e-tags at all.

 If, for arguments sake you had an account with Sanral and your number plate is listed there, why would they need the E-tag to make the connection and not just use the number plate recognition software.

It seems from the above, that it is still a lot more difficult to do it via the camera?
