Abstract

Abstract: The tracking arithmetic in right angle coordination system can not deal with rotated and sized target image，by analyzing the log-polar transform，this paper brings forward a project tracking algorithm based on optical flow in log-polar image.This algorithm can track rotated and sized target image.The experimental results reveal that this approach is efficient，and can deal with translations.Therefore，in this work，the problem of translation estimation in log-polar images is tackled.

Key words: attention mechanism, project, tracking algorithm, log-polar image

摘要： 针对直角坐标系中跟踪算法无法跟踪存在旋转和尺度变化目标图像的问题，在分析对数极坐标变换的基础上，提出了一种对数极坐标域的投影跟踪算法。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，这种采用对数极坐标域的跟踪算法具有很好的实用价值。
