WebSIFT is proposed by David G. Lowe in his paper. ( This paper is easy to understand, I recommend you to have a look at it ). In general, SIFT algorithm can be decomposed into four steps: Feature point (also called keypoint) detection; Feature point localization; Orientation assignment; Feature descriptor generation. WebSIFT (Scale Invariant Feature Transform) is a feature detection algorithm in computer vision to detect and describe local features in images. It was created by David Lowe from the University British Columbia in 1999. David Lowe presents the SIFT algorithm in his original paper titled Distinctive Image Features from Scale-Invariant Keypoints. ikea furniture baby cribs
