second close is calculated at this time. If the ratio is greater than 0.8, it is ignored. This removes 90% of the error match, while only 5% of the correct match is removed. As the article says.This is the summary of the SIFT algorithm. It is highly recommended that you read the original document, which will deepen your understanding of the algorithm. Please keep in mind that this algorithm is protected by patents. So this algorithm is included in the charge module in OpenCV.The SIFT in OpenCVN

After groping, by modifying some parameters, the RHEVH can be installed perfectly on the VMware workstation, so it is much easier to practice.The steps are as follows:650) this.width=650; "Src=" http://ugc.qpic.cn/adapt/0/de3d9619-d680-171d-84ba-aee7b76e2a1a/800?pt=0ek=1
