WebbScale-Invariant Feature Transform (SIFT) SIFT is a computer vision algorithm to extract features from an image. Extracted features from multiple images can be compared, and the same feature on all images can be extracted. Applications for this algorithm include object recognition, image stitching, gesture recognition as well as photogrammetry. WebbObject recognition using feature-based algorithms are generally computationally inten-sive. The scale-invariant feature transform (SIFT) algorithm proposed in 1999 by David Lowe [1], is a classical and well-known algorithm within the eld of computer vision. SIFT algorithm is a feature-based algorithm that can be applied in object recognition ...
