摘要

我们致力于进一步发展我们在图像压缩领域的安全测试。这一阶段的重点是应用Karhunen-Loeve变换(KLT)对车牌图像进行高效编码。汽车车牌是一类特殊的图像，KLT很好地匹配了这一目的。记录一组车牌，生成次优编码库。在此基础上对车牌图像进行了压缩，并给出了压缩结果，包括压缩率与MSE的关系。为了进行比较，还展示了压缩标准图像测试LENA。所提出的有效压缩设计可应用于各种汽车识别系统，如大门、高速公路入口等。最后对结果进行了讨论。

Efficient method for security image data compression

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.
