WebMay 8, 2012 · Scale Invariant Feature Transform (SIFT) is an image descriptor for image-based matching developed by David Lowe (1999, 2004). This descriptor as well as related … The scale-invariant feature transform (SIFT) is a computer vision algorithm to detect, describe, and match local features in images, invented by David Lowe in 1999. Applications include object recognition, robotic mapping and navigation, image stitching, 3D modeling, gesture recognition, video tracking, … See more For any object in an image, interesting points on the object can be extracted to provide a "feature description" of the object. This description, extracted from a training image, can then be used to identify the object … See more Scale-invariant feature detection Lowe's method for image feature generation transforms an image into a large collection of … See more There has been an extensive study done on the performance evaluation of different local descriptors, including SIFT, using a range of detectors. … See more Competing methods for scale invariant object recognition under clutter / partial occlusion include the following.
