In recent years, automatic vehicular license plate recognition (AVLPR) framework has emerged as one of the most significant issues in intelligent transport systems (ITS) because of its magnificent contribution in real-life transportation applications. Restricted situations like stationary background, only one vehicle image, fixed illumination, no angular adjustment of the skewed images have been focused in most of the approaches. An innovative real time AVLPR technique has been proposed in this thesis for the skewed images where detection, segmentation and recognition of LP have been focused. A polar co-ordinate transformation procedure is implemented to adjust the skewed vehicular images. The image gets reorganized in accordance with the image inclined slope by utilizing polar co-ordinate transformation procedure by proper revolving. This includes in the pixel mapping of new image to the old image for getting this Euclidean entity under the projective distortion.
