Abstract

To address the challenge of evaluating modern optical flow computation technology, this paper proposes a corrected evaluation methodology for optical flow of angle error based on the popular Middlebury benchmark. Firstly, a corrected evaluation benchmark is proposed based on the Middlebury benchmark. for flow error statistics, a mathematical expectation is employed instead of the current mathematical average as the expectation can reflect a more appropriate error distribution for the flow result. Secondly, several typical methods of optical flow and four classical test sequences chosen from the Middlebury database are employed to show the improvement attained by using the proposed evaluation methodology. Thirdly, evaluation results of the test methods with both the proposed and Middlebury benchmarks are provided in the experimental section. Finally, the comparison result indicates that the proposed evaluation benchmark can reflect the flow result performance more objectively and appropriately.
