It associates a movement vector to every interesting pixel in a scene, obtained by comparing two consecutive images. First, we fix an orientation based on the circular region information around the keypoint (interest point). Algorithms have a wide variety of applications. Role of Computer in Education: Today learning becomes easy because of computers. Not only does the object needs to be identified, but the identification also needs to be quick enough to render in real-time while it moves. With the advancement in artificial intelligence and, SIFT was proposed in 2004 by David Lowe, the University of British Columbia in his research. This highlights pixels that are different from their neighborhood instead of performing just a foreground and background segmentation. Memory: A computer can store billions of records as per requirement and these records can easily accessible with full accuracy. If an input is the same then output wont be different. Accuracy: A calculation or task performed by a computer is accurate the chances of occurring errors are minimal. It also converges fast had gives reliable results.
