Surf improves the way of feature extraction and description, and uses a more efficient way to complete feature extraction and description. SIFT algorithm has the advantages of stable features, invariability for rotation, brightness and scale transformation, and stability for perspective transformation and noise to a certain extent. Its disadvantage is that its practical application value is not high, and when the image edge is smooth, the extraction of feature points will become more difficult<br>
