In watermarking and data hiding context, it may be very useful to have methods checking the invisibility of the inserted data or at least, checking the objective quality after the mark embedding or after an attack on the watermarked media. Many works exist in the literature dealing with quality assessment mainly focused on compression application. Nevertheless, visual quality assessment should include special requirements that depend on the application context. This chapter presents an extended review of both subjective and objective quality assessment of images and video in the field of watermarking and data hiding applications.
