【摘要】 电子稳像的实时鲁棒性算法,首先对采集到的每帧图像建立高斯金字塔。然后在高斯金字塔的顶层进行初估计,采用图像块法得到整像素的运动估计矢量。精估计采用光流梯度法。为提高鲁棒性,运用简化的M收敛法进行梯度约束。最后阶段采用双线性内插对当前帧与参考帧进行匹准。经测试,该算法效果较好,也能实时运行。更多还原

【Abstract】 At first, the real-time robust algorithm of digital image stabilization establishes the Gauss pyramid based on collected images. Then, the algorithm carries out first estimation on the top layer of Gauss pyramid. The image module algorithm is used to acquire the sports estimation vector of whole pels. The precise estimation adopts light stream gradient algorithm. For improving robustness, simplified M convergence algorithm is used to carry out gradient restriction. At last, the phase adopts bilinear inner insert to match current frame and reference frame. After testing, the algorithm effect is good, and can be carried out in real-time.更多还原
