| Abstract: | The interframe transform coding has been seldom used in practice because of the considerable computational complexity. To reduce the computational complexity, a fast algorithm is proposed in this paper. The algorithm reduces the number of operations by limiting the calculation of transform coefficients without significant quality degradation based on the distribution of
transform coefficients. Then, different modes of transformation are performed according to frame difference. This proposed fast interframe coding, like the MPEG, has an asymmetric property with decoding being much faster than encoding. Computer simulations show that this fast algorithm can significantly reduce the computational burden in interframe transform coding and is even faster than MPEG-like coding. |
