摘要/Abstract

摘要： 提出跨尺度插值方法，获取高质量、高帧率和高分辨率的运动图像序列，以增强空间对接任务中图像的运动平滑性，流畅地再现空间图像运动细节。提出基于视觉对应的关注域探测方法，有效地缩小插值帧的预测范围，实现关注尺度改变;提出基于一致敏感哈希的帧插值方法，生成高质量的插值帧，实现帧率尺度改变;提出基于区域的运动序列插值方法，提高关注域插值细节，实现分辨率尺度改变。实验结果表明，相比于已有的方法，可取得更好的视觉效果和更高的客观评价指标值。

Abstract: In order to enhance the motion smoothness and reproduce motion details in the space docking mission, a transcale interpolation method is proposed to obtain motion image sequences which have high quality, high frame rates and high resolutions. The attention region detection approach based on visual correspondence is presented to reduce the prediction ranges of interpolation frames, so as to complete the change of attention scale. The frame interpolation approach based on coherency sensitive hashing is proposed to capture high quality interpolation frames, so as to complete the change of frame rate scale. The motion sequence interpolation approach based on regions is proposed to enhance the detail quality of attention regions, so as to complete the change of resolution rate. Experimental results show that the proposed method achieves better visual effects and higher objective index values, compared to the existing methods.

Key words: image interpolation, transcale interpolation, attention regions
