Fuzzy transforms for compression and decompression of color videos

We use the fuzzy transforms method for coding/decoding color frames of videos and we compare the results with the same frames reconstructed with the standard JPEG method. We classify all the frames in intra-frames and predictive frames by adopting a similarity measure based on the Lukasiewicz t-norm and a pre-processing phase to determine an optimal similarity threshold value. We consider particular frames, called -frames, obtained from a suitable difference between an intra-frame and a predictive frame. In our tests we have used the videos downloaded from URL http://sampl.eng.ohiostate.edu/~sampl/database.htm. Under high compression rates, the PSNR (Peak Signal to Noise Ratio) of the frames obtained with the fuzzy transforms method is averagely close to the PSNR obtained with the JPEG method.
