Definition
Scale-Invariant Feature Transform: A computer vision algorithm for detecting and describing local features in images.
Detailed Explanation
SIFT is a robust feature detection method that identifies keypoints invariant to scale rotation and illumination changes. It generates feature descriptors through a process of keypoint detection orientation assignment and descriptor computation. These features are particularly useful for object recognition and image matching tasks.
Use Cases
1. Image matching 2. Object recognition 3. Panorama stitching 4. 3D reconstruction
