It judges the yellow pixel with YSC color space directly,afterwards detects connected region in order to delete the short yellow line,then fits the break points by using close operation in Mathematical Morphological Metheods,finally use the Marr wavelet transform to pair yellow line.
介绍了在交通视频影像中一种道路黄线的识别方法,首先通过YSC计色制对黄色像素点进行判别,然后用连通区检测的方法排除伪黄线,并通过数学形态学中的闭运算对较小的局部断裂黄线进行拟合,最后使用Marr小波变换修整黄线。
补充资料：关系的闭包
关系的闭包
设r是非空集合a上的二元关系，在关系r中，添加最少的有序对，新关系用r¢表示，使得r¢具有关系的自反(对称、传递)性质，r¢就是r的自反(对称、传递)闭包，记作r(r) ，s(r)和t(r)。：
