When the relative factors, such as the inherent correlation in video-signal, the presistence characteristic of picture tube, have been considered comprehansively, the pseudo-random dot scan and the pulse-code modulation are then adopted in the system. For this way, compressing the video-signal of IMHZ bandwidth to the rate of Ibit/pel is obtained. The experimental results show that the restored picture...

This paper presents a high efficiency predictive coding scheme for multi-level images. In this coding scheme, continuous picture signals are considered as m-th order Markov process; the prediction value of each picture element is determined by a nonlinear function of its neighboring picture elements; and the nonlinear quantization is determined by the type of the difference of its neighboring picture elements. The proposed scheme can fully utilize the characteristics of picture signals within the neighborhood of each picture element, with adaptive nonlinear prediction and quantization for each individual picture element. Therefore, higher coding efficiency is obtained, especially in the region of contours and textures of images. Computer simulations show that the reconstructed images with transmission rate of entropy value 2 bits/pel hardly show any visible degradations by comparison with the original images. The proposed nonlinear predictive coding scheme has higher efficiency and simpler implementation by comparison with the existing predictive coding methods. It is suitable for high-speed real-time transmission of different kinds of images.

本文提出了多值制图象的高效率预测编码方法。它把各类连续变化的图象信号当作m阶Markov过程,每个象素的预测值取决于其邻近象素的非线性函数,而对预测误差的非线性量化,则取决于其邻近象素增量状态的类型。这种编码方法,充分利用图象信号在每个象素邻近区域的具体变化特点,逐个象素进行自适应非线性预测及量化。因此,提高了编码效能,特别是在图象的轮廓边沿或交织结构部位。计算机模拟表明,当传输信号的熵值为2bits/pel时,主观上难以发现图象损伤。本文的编码方法与其他高效率预测编码方法相比,不仅预测效率高,而且结构简单,适用于各种图象的高速实时传输。
