%将三个颜色分量合成为一维特征向量：L = H*Qs*Qv+S*Qv+v；Qs,Qv分别是S和V的量化级数, L取值范围[0,71]
%取Qs = 3; Qv = 3
for i = 1:M
for j = 1:N
for k = 1:O
L(i,j,k) = H(i,j,k)*9+S(i,j,k)*3+V(i,j,k);
end
end
end
%计算L的直方图
for i = 0:71
Hist(i+1) = size(find(L==i),1);
end
Hist = Hist/sum(Hist);
请问错哪，怎么改？

路过，我是个新手，看不懂。小弟有个难解请求您帮帮忙，希望您可以帮我，谢谢。将车牌转换成HSV颜色空间后，怎样提取出蓝底白字车牌的蓝色和白色的H、S、V三个分量的范围？？？小弟在此感激涕零，可以直接回复，或者联系QQ：534136830
