| 摘 要： | 针对从隔行扫描的电视场图像获得高质量的逐行扫描帧图像,提出了一种从隔行扫描到逐行扫描的转换算法。该算法通过在隔行/逐行转换中引入运动估计技术,找出相邻两场图像间的运动矢量,然后在场间行内插值时进行图像调整来消除由于图像错位引起的运动模糊,生成具有高垂直分辨率的逐行图像。算法中针对这一特定应用场合,设计了一种运动估计方法。

| Abstract: | An interlace/progressive transforming algorithm which is to get high quality progressive frame picture from interlace field picture is proposed. In this algorithm, motion estimation technology is used to find out the motion vector between the two neighboring field pictures. Then in the process of line interpolation, the motion vector is used to adjust the first field picture's location. The motion blur, which is caused by image slip, can be eliminated. The progressive picture that is produced by the algorithm possesses high vertical resolution. In the algorithm, we design a special motion estimation approach to fit in with this application. |
