WebJul 6, 2024 · Answers (1) Each feature point that you obtain using SIFT on an image is usually associated with a 128-dimensional vector that acts as a descriptor for that specific feature. The SIFT algorithm ensures that these descriptors are mostly invariant to in-plane rotation, illumination and position. Please refer to the MATLAB documentation on Feature ... 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 feature vectors, each of which is invariant to … See more There has been an extensive study done on the performance evaluation of different local descriptors, including SIFT, using a range of detectors.
