mycombine.m

matlab车牌识别程序 我找了好久才找的 觉得好顶一个

function [rectange,rec_center,rec_ratio]=mycombine(rec,heigth,width,T1,T2)
%将临近区域进行合并
L_rec=length(rec);
rectange=zeros(heigth,width);
for i=1:L_rec
    for j=i+1:L_rec
        same=(min(rec{i}(2),rec{j}(2))-max(rec{i}(1),rec{j}(1)))/...
            min(rec{i}(2)-rec{i}(1),rec{j}(2)-rec{j}(1));
        h=abs([rec{i}(3)-rec{j}(3),rec{i}(3)-rec{j}(4),...
            rec{i}(4)-rec{j}(3),rec{i}(4)-rec{j}(4)]);
        if(same>=T1&&min(h)<=width*T2)
            rec{i}=[min(rec{i}(1),rec{j}(1)),max(rec{i}(2),rec{j}(2)),...
                min(rec{i}(3),rec{j}(3)),max(rec{i}(4),rec{j}(4))];
        end
    end
end
for i=1:L_rec
    rectange(rec{i}(1):rec{i}(2),rec{i}(3):rec{i}(4))=1;
end

boundaries = bwboundaries(rectange);            %调用函数 bwboundaries
k=length(boundaries);
rectange=cell(1,k);
for i=1:k
   b = boundaries{i};
   rectange{i}(1)=min(b(:,1));rectange{i}(2)=max(b(:,1));%矩形的行起点与终点
   rectange{i}(3)=min(b(:,2));rectange{i}(4)=max(b(:,2));%矩形的列起点与终点
   rec_center{i}=[fix((rectange{i}(1)+rectange{i}(2))/2),fix((rectange{i}(3)+rectange{i}(4))/2)];%矩形中心
   rec_ratio(i)=(rectange{i}(4)-rectange{i}(3))/(rectange{i}(2)-rectange{i}(1));%矩形长宽比
end
