| 摘 要： | 同时考虑算法的精度和效率,以常用的基于梯度的运动估计算法为例,提出了一种运动估计算法的性能评估方法.在该方法中,以表征算法精度的偏差为横坐标,以表征算法效率的执行时间为纵坐标,构建了一个偏差一时间二维性能评估坐标系,通过设置算法的不同参数,绘制偏差一时间性能评估曲线.性能评估实例表明了所提出的偏差-时间性能评估方法在评估基于梯度的运动估计算法性能时的有效性.

| Abstract: | Gradient-based algorithms for motion estimation taken as an example for evaluating performance,a performance evaluation method of motion estimation algorithms is proposed through considering accuracy as well as efficiency.In this method,the bias is used as the criterion for accuracy,and the execution time of algorithm is used as the criterion for efficiency.A two-dimension bias-time coordinate system of evaluating performance is constructed by using the bias as one coordinate and execution time as the other... |
