This paper proposes a method of reduced-reference image quality assessment based onwatermarking algorithm in underwater acoustic channel. By embedding the watermark image intothe original one, then delivering the combined image through the channel distortion, the samechannel distortion would be exposed to the original and the watermark image. In the receiver,weuse the blind extraction methods to recover the watermark image and use the watermarkdegradation to evaluate the quality of the original one. In this paper,we build three kinds ofchannels: AWGN channel, Rice fading channel and GB model channel to validate the feasibility ofthe method which would be used in the underwater acoustic channel.
