Fast normalized cross correlation
WebThe match_template function uses fast, normalized cross-correlation [ 1] to find instances of the template in the image. Note that the peaks in the output of match_template correspond to the origin (i.e. top-left corner) of the template. [ 1] J. P. Lewis, “Fast Normalized Cross-Correlation”, Industrial Light and Magic. WebJun 3, 2024 · In this paper, regenerative braking control of electric vehicles is investigated based on multi-source information such as image recognition, GPS and vehicle running parameters. Firstly, the fast normalized cross-correlation (FNCC) algorithm is applied to identify the speed limit traffic signs. Then the vehicle speed is intelligently controlled …
