An image-sequence storage was made and a computer simulation system for the data compression of image sequences sects constructed. A new algorithm of the 3-dimensional TAT(3-D TAT) system was developed by using the simulation system. The 3-D TAT system of the algorithm was implemented. The hardware of the constructed 3-D TAT system is very simple; for example, the encoder has about 10,000 gates only. The compression of high-resolution picture signals was successfully demonstrated. The interframe interpolation mode of the 3-D TAT system greatly improves still picture quality; no difference was observed between the reconstructed and original pictures. The 3-D TAT algorithm selects the interframe interpolation mode for moving pictures and reconstructs them very well. The 3-D TAT system has fast response to the scene change. When the picture is switched from one still scene to another still scene, the number of the interframe interpolation blocks decreases in the first frame after the scene change, and then increases rapidly reaching the steady, state in about 4 frames. Thus, the 3-D TAT system employing the new algorithm is very effective for the compression of high-resolution pictures.

制作了图像序列存储器，并建立了图像序列段数据压缩的计算机模拟系统。利用该仿真系统开发了一种新的3-D达特系统算法。实现了该算法的三维达特系统。所构造的三维达特系统的硬件非常简单，例如，编码器只有大约10，000个门。高分辨率图像信号的压缩被成功地证明。三维达特系统的帧间插值模式大大提高了静止图像的质量，重建图像与原始图像没有差别。3-D达特算法选择了帧间插值的方式对运动图像进行了很好的重建。三维达特系统对场景变化的响应速度快。当画面从一个静止场景切换到另一个静止场景时，帧间插值块的数量在场景改变后的第一帧中减少，然后快速增加，在大约4帧中达到稳定状态。因此，采用新算法的三维达特系统对高分辨率图像的压缩是非常有效的。
