摘要
提出并验证了基于区域匹配的二维超声心动图序列速度场估计方法。Singh和Allen (CVGIP: Image Understanding, vol. 56, p. 152-77, 1992)提出的方法在相似性指数的选择上进行了修改。基于合成图像序列的测试结果表明，模板匹配方法比基于梯度的方法具有更强的鲁棒性和准确性，但计算时间要长得多。
Region based matching for velocity field computation in 2-D echocardiography
Methods based on region matching to estimate velocity field on sequences of 2-D echocardiograms are presented and tested. The method proposed by Singh and Allen (CVGIP: Image Understanding, vol. 56, p. 152-77, 1992) has been modified in the choice of the similarity index. Results of test based on sequences of synthesized images show that template matching methods are more robust and accurate than gradient based methods, while on the other hand computation time is much higher.<>
