| Tóm tắt≠ | 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. | Template matching is a straightforward technique for locating a known pattern (template) within a larger image. By sliding a template image across the target image and computing a similarity measure at each position, template matching identifies locations where the template appears. It is effective for simple object detection when templates are well-defined and appearance variation is limited. |
