WebAug 20, 2014 · Sequential implementations of SIFT are known to have high execution times. The open source sequential implementation SIFT++ [ 13] takes around 3.3 s on a 2.4 GHz processor for a 640 × 480 image. This can allow a maximum frame rate of around 0.31 fps, which is much less than the minimum frame rate expected.
