WebJan 1, 2024 · When matching feature points, the 9 × 9-pixel block is used to overcome the sensitivity to noise, and the magnitude of the gray value in the pixel block is determined to generate the corresponding feature descriptor, which improves the algorithm’s resistance to noise and rotation invariance. WebJan 31, 2024 · Feature points refer to points or blocks that can represent their characteristics in a certain area during camera movement, and the feature points extraction process includes: (1) Acquire the image and extract the image feature points. (2) Process the extracted feature points and complete the feature matching.
