In this paper we focus on the recognition
of a wide set of triangular traffic signs
using a novel algorithm, the Number of Peaks.
在本文中,我們專注於使用一種新的演算法,
叫作「反轉點的數目」,
去辨識多樣的三角形交通標誌。
Once a traffic sign is detected,
three horizontal lines (T, H, B)
and three vertical lines (R, V, L)
across the image are used to recognize the sign.
一旦檢測到交通標誌的影像,
就畫出三條水平線(T,H,B)橫跨影像,
和三個垂直線(R,V,L)直跨影像,
用於識別標誌。
The number of crossings from a black pixel to a white pixel (peak)
on each line is calculated.
每條線會經過黑色的像素再經過白色的像素,
計數「由黑轉白之處」(反轉點)有幾個。
A simple and fast decision-tree-like search algorithm
uses the number of peaks
to differentiate between the triangular road signs.
再把這些「反轉點」的數目,
作成一個簡單而快速的類似搜尋「決策樹」的演算法,
來判別不同的三角形路標。
