4.4 Performance Analysis and Discussions
A total of 100 images were used to evaluate the performance of the preprocessing,
character extraction and recognition. The result obtained was tabulated in Table 4.3
where the percentage of the perfect preprocessing of plate region is 93%, percentage of
character extraction is 98% and percentage of recognition is 91%. Table 4.4 shows the
example of failure in pre-processing stage while Table 4.5 shows the example of failure
in character extraction.
