Effects of Character Recognition with Shell Histogram Method Using Plate Characters

Character recognition is a study that has been used in various fields for many years. in character recognition, the aim is to identify the various texts, letters and symbols in the images as accurately and quickly as possible. in addition to the optical character recognition (oct) method, which is used as a very common method, there are many feature extraction methods in which character image features are compared. in this study, which is presented as another feature extraction method, the letters on the license plates are recognized. the characters were examined using the circular shape histogram technique and histograms were obtained from the sectors within the circular regions. feature vectors for letter characters were created using character pixel densities in sectors. feature vectors are analyzed linearly and an alternative quick character recognition method is presented. with the proposed method, the element numbers of the feature vectors are kept constant. in this way, both the processing speed is increased and the processing speed variations are minimized. the results show that the proposed method requires lesser parameters than the oct method, but also has a significant success rate according to known feature extraction methods.
