This two-year research aims at a development of a novel compression coding technique for high-frame-rate motion images which maximizes the image quality within a restricted transmission bit rate. The detailed objects include (1) a development of an adaptive and local frame rate control technique for high-frame-rate motion images, (2) a derivation of a prediction technique for the temporal image quality for image sequences generated by (1), and (3) a development of a coding algorithm which maximizes the spatio-temporal total image quality based on the results (1) and (2).In 2005, we have investigated the issues (1) and (2), and proposed an adaptive frame-rate control technique which can adapt to non-stationary motion while suppress motion jaggyness.Based on the technique obtained in 2005, we have tried to develop a novel MPEG-4 encoder in 2006, which encodes a target image sequence with the "optimal frame rate" derived by maximizing the estimated total image quality (MOS). The resulting image sequences were compared to fixed-frame-rate ones to confirm the effectiveness of our approach.From these results, we believe that our final goals have been completely achieved.

这项为期两年的研究旨在开发一种新的高帧速率运动图像压缩编码技术，在有限的传输比特率下最大化图像质量。具体目标包括(1)开发用于高帧速率运动图像的自适应和局部帧速率控制技术，(2)推导由(1)生成的图像序列的时间图像质量预测技术，以及(3)基于结果(1)和(2)开发最大化时空总图像质量的编码算法。2005年，我们研究了问题(1)和(2)，并提出了一种能够在抑制运动抖动的同时适应非静止运动的自适应帧速率控制技术。基于2005年获得的技术，我们在2006年尝试开发了一种新的MPEG4编码器，它以最大化估计的总图像质量(MOS)来获得最佳帧速率来编码目标图像序列。将得到的图像序列与固定帧速率的图像序列进行比较，以验证该方法的有效性。从这些结果中，我们相信我们的最终目标已经完全实现。
