Abstract We devote to the further development of our tests in the field of image compression for security purposes. This phase has been oriented to the application of Karhunen-Loeve Transform (KLT) for efficient coding of car plate images. The car plate is a special class of images and the KLT is well matched to this purpose. A set of car plates was recorded and the suboptimal coding base was generated. Applying this base some examples of car plate images have been compressed and the compression results are presented including the dependence of compression rate vs MSE. The compressed standard image test LENA is also shown for comparison. The suggested efficient compression is design to be applied in various car identification systems such as entrance gates, highway entries etc. Finally the results are discussed.
