WebFeb 3, 2024 · SIFT (Scale Invariant Feature Transform) Detector is used in the detection of interest points on an input image. It allows identification of localized features in images … WebSIFT Detector. Scale-Invariant Feature Transform (SIFT) is another technique for detecting local features. The Harris Detector, shown above, is rotation-invariant, which means that the detector can still distinguish the corners even if the image is rotated. However, the Harris Detector cannot perform well if the image is scaled differently.
