WebThis DMatch object has following attributes: DMatch.distance - Distance between descriptors. The lower, the better it is. DMatch.trainIdx - Index of the descriptor in train descriptors; DMatch.queryIdx - Index of the descriptor in query descriptors; DMatch.imgIdx - Index of the train image. knnMatch Usage. In this example, K = 2. Web13 de jan. de 2024 · matches = bf.match (descriptors1, descriptors2) So, now we have our matches. The next step is to sort them according to their distance.
