In this paper, the authors propose an objective picture quality measurement method in the absence of reference pictures. The proposed method assumes TV transmission chains - especially tandem connection of codecs, and enables an automatic objective measurement of the picture quality. In the proposed method, invisible markers are embedded inti original pictures by use of spread spectrum data-hiding method and the picture quality is estimated by using the detectioni rate of the maekers. Computer simulation experiments show that the proposed method provides highly accurate estimation of RSNR while retaining the degradation by inbisible markers negligible.
