Abstract

This paper presents a comparative study of performance metrics applied to color images with invisible digital watermark. The imperceptibility of the watermark and the distortion that can cause in the image are important factors in the evaluation of the invisible watermark insertion algorithms and usually this is done through the performance metrics. Thus, the aim of this article is to analyze and evaluate the results obtained through different performance metrics. The metrics chosen through literature were: PSNR, MPSNR, MSSIM, ΔEab and ΔE00.
