下面這是一段直方圖等化對彩色圖像的運算僅會秀出原圖像及修改後圖像請問我要加上什麼程式碼才能讓程式多秀出等化後的直方圖感謝 sourcePic=imread('1.jpg'); [m,n,o]=size(sourcePic); figure,imshow(sourcePic,[]); %grayPic=rgb2gray(sourcePic); grayPic=sourcePic(:,:,1); gp=zeros(1,256); %計算各灰階出現的機率 for i=1:256 gp(i)=length(find(grayPic==(i-1)))/(m*n); end newGp=zeros(1,256); %計算新的各灰階出現的機率 S1=zeros(1,256); S2=zeros(1,256); tmp=0; for i=1:256 tmp=tmp+gp(i); S1(i)=tmp; S2(i)=round(S1(i)*256); end for i=1:256 newGp(i)=sum(gp(find(S2==i))); end newGrayPic=grayPic; %填充各像素點新的灰階值 for i=1:256 newGrayPic(find(grayPic==(i-1)))=S2(i); end nr=newGrayPic; grayPic=sourcePic(:,:,2); gp=zeros(1,256); %計算各灰階出現的機率 for i=1:256 gp(i)=length(find(grayPic==(i-1)))/(m*n); end newGp=zeros(1,256); %計算新的各灰階出現的機率 S1=zeros(1,256); S2=zeros(1,256); tmp=0; for i=1:256 tmp=tmp+gp(i); S1(i)=tmp; S2(i)=round(S1(i)*256); end for i=1:256 newGp(i)=sum(gp(find(S2==i))); end newGrayPic=grayPic; %填充各像素點新的灰階值 for i=1:256 newGrayPic(find(grayPic==(i-1)))=S2(i); end ng=newGrayPic; grayPic=sourcePic(:,:,3); gp=zeros(1,256); %計算各灰階出現的機率 for i=1:256 gp(i)=length(find(grayPic==(i-1)))/(m*n); end newGp=zeros(1,256); %計算新的各灰階出現的機率 S1=zeros(1,256); S2=zeros(1,256); tmp=0; for i=1:256 tmp=tmp+gp(i); S1(i)=tmp; S2(i)=round(S1(i)*256); end for i=1:256 newGp(i)=sum(gp(find(S2==i))); end newGrayPic=grayPic; %填充各像素點新的灰階值 for i=1:256 newGrayPic(find(grayPic==(i-1)))=S2(i); end nb=newGrayPic; res=cat(3,nr,ng,nb); figure,imshow(res,[]); -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 61.231.128.224 ※ 文章網址: http://www.ptt.cc/bbs/MATLAB/M.1417853821.A.F81.html
