ANPR(Automatic number-plate recognition)/ALPR accuracy improvement or New ANPR system with source

We havse developed ANPR/ALPR system for Taiwan license plate recognition based on open source using c++. We use Hough transfrom to find license plate location and do tranform, and use Tesseract to do ocr. We need to handle skewed license plates, blurred license plate, blurred due to reflective light, multiple license plates, and license plates in different resolution. We can provide some samples if needed. We need an experienced partner to help acheive 95% or above accuracy.
On the other hand, the souce code we based on is around 7 years ago. If you have new, high accuracy designed is also welcomed. We have flexible cooperation model. However, we do need source code and training tools.
