Bayesian high-resolution reconstruction of low-resolution compressed video. Segall, C., Molina, R., Katsaggelos, A., & Mateos, J. In Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), volume 2, pages 25–28, 2001. IEEE, IEEE. Paper doi abstract bibtex A method for simultaneously estimating the high-resolution frames and the corresponding motion field from a compressed low-resolution video sequence is presented. The algorithm incorporates knowledge of the spatio-temporal correlation between low and high-resolution images to estimate the original high-resolution sequence from the degraded low-resolution observation. Information from the encoder is also exploited, including the transmitted motion vectors, quantization tables, coding modes and quantizer scale factors. Simulations illustrate an improvement in the peak signal-to-noise ratio when compared with traditional interpolation techniques and are corroborated with visual results.
