WebNov 16, 2024 · In this section we will discuss using the Ratio Test to determine if an infinite series converges absolutely or diverges. The Ratio Test can be used on any series, but unfortunately will not always yield a conclusive answer as to whether a series will converge absolutely or diverge. A proof of the Ratio Test is also given. WebMar 8, 2024 · SURF is better than SIFT in rotation invariant, blur, and warp transform. SIFT is better than SURF in different scale images. SURF is three times faster than SIFT because of the use of integral image and box filters. [1] Just like SIFT, SURF is not free to use. 3. ORB: Oriented FAST and Rotated BRIEF
