WebJan 3, 2016 · The SIFT descriptor vector is a feature vector. "Descriptor vector" and "feature vector" are synonyms in this context. Most of the descriptions of SIFT I've seen use the phrase "descriptor vector", but occasionally they'll refer to it as a "feature vector" or refer it to as "SIFT features", perhaps to draw upon intuition from machine learning. WebScale-Invariant Feature Transform ( SIFT )—SIFT is an algorithm in computer vision to detect and describe local features in images. It is a feature that is widely used in image … WebLocal features are used for many computer vision tasks, such as image registration, 3D reconstruction, object detection, and object recognition.
