【摘要】 针对直角坐标系中光流跟踪算法无法跟踪存在旋转和尺度变化目标图像的问题,在分析Horn-Schunck经典光流计算公式基础上,提出了一种对数极坐标域的梯度跟踪算法。该算法可以对存在旋转和尺度变化的运动目标实施跟踪,通过实验证明了这种方法在处理运动图像变化时是有效的。因而,这种用对数极坐标域的跟踪算法有一定的实用价值。更多还原

【Abstract】 Aim at the optical flow tracking arithmetic in right angle coordination system can not deal with rotated and sized target image,by analyzing the Horn-Schunck sutra optical flow arithmetic formula,bring forward a gradient tracking algorithm based on optical flow in log-polar image.This algorithm can track rotated and sized target image.As the experimental results reveal,this approach is efficient,can deal with translations.Therefore,in this work,the problem of translation estimation in log-polar images is tackled.更多还原
