In this paper, we propose the algorithm that
used to identify car license plate that the capture images
come in degraded version by combining a PWS filtering
technique with a 2DPCA algorithm. From experiment
results, our algorithm has three advantages. First, it can be
operated to the image directly without transforming the
structure of the image, which is two dimensional data, into
a vector. Second, it can be implemented with less burden
of computation and requires less memory. At last, less time
is required to restore the image.
