Does anyone know a nice way to automatically blur /censor number plates /license plates from jpegs preferably in javascript!? Or do all of you do this by hand? Couldn't figure one out yet...
The hard part is going to be reliably recognizing the area of the image that is the number plate. Although there are image processing libraries for JavaScript, I'm not sure they're suitable to what you want to do.
Unless you have a zillion of these, blur them by hand; it'll be less work.
