User-interface for relative performance evaluation of compression techniques

Several techniques for video compression have appeared in literature namely JPEG, MPEG, H.263, wavelet, vector quantization, sub-bands, etc. In this paper, we present a user interface design which allows subjective comparison by simultaneous display of the encoded sequences (along with the original) at a variety of compression ratios in a synchronized manner. The proposed interface is extremely useful for relative performance evaluation of various compression techniques and can be easily extended to incorporate evaluation of new compression techniques.
