A new integration formula and its local truncation error are presented on the basis of non-iso-interval Newton interpolation. The new integration algorithm appears to be more stable and efficient than the methods of Gear, BDF, PBD. Its numbers of the integration steps, Newton iterations, Jacob modifications may be decreased significantly. The self-start, automatic variating order and step of the integration, the interpolation of output points and the structure of the integration program are discussed and the...

A new integration formula and its local truncation error are presented on the basis of non-iso-interval Newton interpolation.

Its numbers of the integration steps, Newton iterations, Jacob modifications may be decreased significantly. The self-start, automatic variating order and step of the integration, the interpolation of output points and the structure of the integration program are discussed and the effect of the algorithm is assessed by using numerical caculations.

An adaptive block truncation coding method is proposed. Results obtained by computer simulation and analysis of the experimental data show that with nearly the same subjective and objective image quality as the Block Truncation Coding Method, the compression ratio is increased to 6.1-6.36 and the effect of eliminating the white noise is evident.

本文提出一种自适应分块截断编码方法。计算机模拟实验与数据分析的结果表明,在图象主、客观质量基本保持不变(相对于分块截断编码方法)的前提下,此方法使编码后的压缩比提高到6.1~6.36,并对消除白噪声有明显的作用。

Based on the essence of the Gibbs phenomenon, the ideal filtering characteristics, the time window characteristics, the spectral window characteristics, the autocorrelation function of band-limited white noise, the leakage effect and the restoration of discrete sampling signal in signal spectrum analysis are discussed.
