| 摘 要： | 提出了一种基于多尺度运动边缘检测的图像序列参数估计方法。通过多尺度运动边缘检测,将图像的能量集中到边缘上,得到噪声污染小、边缘连续清晰的运动目标;并利用小波变换特征匹配方法,得到运动矢量。该方法既利用了空域帧内灰度信息又利用了时域帧间信息,能精确地估计目标的运动参数。

| Abstract: | In this paper,an new method of parameter estimating based on the edge detection of movement is proposed.By mutiscale edge detection of movement ,the image energy is focused on the image edge,motion object of less noise with clear and continuous edge is got.Movement vector is gotten with matching algorithm of the wavelet transform fea-tures.In the method proposed in the paper,not only the gray level information in the frames of spatial field is used,but also the information among the frames in different frequency fields is used,therefore the movement parameters of ob-jects can be estimated accurately. |
