| सारांश≠ | SIFT (Scale-Invariant Feature Transform) is a method for detecting and describing distinctive local features in digital images. Introduced by David Lowe in 1999, SIFT extracts keypoints that remain invariant to scale, rotation, and illumination changes, making it highly robust for image matching and object recognition tasks. | Scale-space theory, developed by Witkin and Lindeberg, provides a principled mathematical framework for analyzing images at multiple scales simultaneously. By treating scale as an explicit dimension and using Gaussian blurring, scale-space theory enables detection and analysis of features at appropriate scales, solving the fundamental problem of 'which scale should I analyze at?' |
