Abstract

A method to estimate the PSNR of transmitted video quality based on the reduced reference method is proposed. We previously studied PSNR estimation using the image feature extraction method based on the spread spectrum and Walsh-Hadamard transform (WHT); however, the conventional method is problematic because large bandwidth is required for the transmission of image features. We therefore propose an improved method that reduces the information amount of the image features. The image feature is expressed by the parity of the quantized level of the WHT coefficients and requires only 1 bit for one image feature while the conventional method requires 8-11 bits for each image feature. Computer simulations show that precise picture quality evaluation is possible at one eighth as much bitrate of the data circuit as the conventional method.
