WebMay 27, 2024 · For drawing the KeyPoint, we use drawKeypoints() function. Its syntax is: cv.drawKeypoints(image, keypoints, outImage[, color[, flags]]) Parameters: image: It is the image from which keypoints have to be obtained. keypoints: These are the obtained keypoints from the source image. outImage: It is the output image. color: The color for the … WebJul 6, 2024 · With the development of societies, the exploitation of mountains and forests is increasing to meet the needs of tourism, mineral resources, and environmental protection.

WebLike we used cv2.drawKeypoints() to draw keypoints, cv2.drawMatches() helps us to draw the matches. It stacks two images horizontally and draw lines from first image to second image showing best matches. There is also cv2.drawMatchesKnn which draws all the k best matches. If k=2, it will draw two match-lines for each keypoint. WebMar 15, 2024 · 例如,下面的代码演示了如何对图像进行 SIFT 特征检测并在图像中绘制关键点: ``` import cv2 import numpy as np # Load the image img = cv2.imread("image.jpg") # Create a SIFT object sift = cv2.SIFT() # Detect keypoints and compute descriptors keypoints, descriptors = sift.detectAndCompute(img, None) # Draw keypoints on the … include shell in powershell gui
