Web3 de jan. de 2024 · Feature detection is the process of checking the important features of the image in this case features of the image can be edges, corners, ridges, and blobs in the images. In OpenCV, there are a number of methods to detect the features of the image and each technique has its own perks and flaws. Web29 de abr. de 2024 · Measure difference as Euclidean distance between feature vectors: Several possible matching strategies: Return all feature vectors with d smaller than a threshold. Nearest neighbor: feature vector with smallest d. Nearest neighbor distance ratio: d1, d2: distances to the nearest and 2nd nearest neighbors. If NNDR is small, nearest …
Web8 de jan. de 2013 · This information is sufficient to find the object exactly on the trainImage. For that, we can use a function from calib3d module, ie cv.findHomography (). If we pass the set of points from both the images, it will find the perspective transformation of that object. Then we can use cv.perspectiveTransform () to find the object.
