The paper is devoted to the impacts of image compression algoritms on security image data. It compares three fundamentally different evaluation techniques of image – objective criteria, subjective criteria and identification. We have selected two typical security image data (a car plate and a face) with different initial quality and we applied three different compression techniques – two professional (JPEG and LuRaWave – LWF) and one implemented (Karhunen-Loeve . transform KLT) [l]. A set of compressed images differing in compression rate was derived from each original image data. Finally the MSE as an objective criterion, the subjective image quality according to the ITU-R Rec. 500 and the identification measure were evaluated and compared.
