2244 为增强工业级机器视觉系统的实时性和稳定性,本文提出一种基于等积环投影与 Zernike 矩的具有旋转不变性的快速模板匹配方法, In order to enhance the real-time performance and stability of industrial-level machine vision systems, This paper proposes a fast template matching method with rotation invariance based on equal-area ring projection and Zernike mo-ments.
2245 该方法采用由粗到精匹配策略,在粗匹配阶段以等积环投影向量作为特征进行匹配得到候选点集,再基于 Zenrike 矩进行精确匹配。 The method uses a coarse-to-fine matching strategy. The coarse matching stage uses the equal-area ring projection vector as the feature to obtain the candidates, and then use Zenrike moments to accurately match in candidates.
2246 主要创新点为提出复杂度低、抗噪性强和具有旋转不变性的等积环投影向量特征,并利用圆对称性在八分圆法基础上进一步降低 Zernike 矩计算量。 The main contributions of this paper are proposing the equal-are ring projection vector feature with low complexity, noise insensitive and rotation invariance, and further reducing the computational cost of Zernike moments based on the octant circle method u-sing circular symmetry.
2247 经理论分析和实验对比验证,此法在保障匹配精度前提下,其匹配速度胜于当前同类最优算法,且对高斯噪声及线性亮度变化有强鲁棒性。 Theoretical analysis and experimental results show that the proposed method is faster than the state-of-the-art algorithm under high matching accuracy, and it is robust to Gaussian noise and linear brightness variations.

2250 首先,使用非刚性稠密块匹配计算图像序列初始最近邻域场,其次根据图像相邻块区域的相似性消除初始最近邻域场中的非一致性区域以得到准确的图像最近邻域场。 Firstly, we utilize the non-rigid dense patch matc-hing to compute the initial nearest neighbor field between the consecutive frames, and eliminate the inconsistent regions of the computed nearest neighbor field according to the consistency of the neighboring patches in the image to obtain an accu-rate image nearest neighbor field.
2251 然后,在图像金字塔分层计算框架下,将图像最近邻域场引入基于非局部约束的 TV-L1 光流估计模型,通过 Quadratic Pseudo-Boolean Optimization(QPBO)融合算法在金字塔分层图像光流计算时对 TV-L1 模型光流估计进行大位移运动补偿。 Secondly, we merge the nearest neighbor field into the TV-L1(Total Variational with L1norm, TV-L1)optical flow model, and employ the nearest neighbor field to compensate the large displacement optical flowof TV-L1 model by using the quadratic pseudo-Boolean optimization (QPBO)fusion algorithm during the coarse-to-fine computation scheme.
