Enhanced car number plate recognition (ECNPR) system by improving efficiency in preprocessing steps

In this paper, we develop an enhanced car number plate recognition (ECNPR) system that is capable of recognizing different design and font styles of car number plates. Our contribution is threefold. Firstly, we use multiple templates matching for recognition of characters, i.e. of various types of font and size. Secondly, the removal of noise by dynamically adjusting the pixel value. Lastly, we create and make use of a more challenging dataset which is comprised of different font style and design of number plates. The results show that the enhancement of CNPR proposed system yields better results in terms of false positive and false negative values.
