为提高灰度投影稳像算法的速度,提出一种等间隔快速投影算法:参考帧图像每行(列)进行投影,待稳定帧图像的投影区域进行等间隔行(列)投影,所有的投影行(列)内等间隔取像素值,将2帧图像的投影曲线进行遍历相关运算,得出图像的运动矢量.通过分析相关曲线,得出其单峰性的特点.实验结果表明,该算法可保持传统灰度投影算法的稳像精度,运算量显著减小,计算速度大大提高.

In order to accelerate gray projection and image stabilization algorithm, put forward a uniformly-spaced allegro algorithm: project each column (row) of the reference frame image, and process uniformly-spaced column (row) projections among the proposed stable frames' projection area. Fetch pixel value among equal intervals of all projection columns (rows). Put up ergodic operations of the two frame images' projection curve, thus obtain moving vectors of the image. Then through analyzing relation curve, find its features of unimodality. Experiment result shows the algorithm can keep precision of traditional algorithm, while can simplify and accelerate the calculation.
