如果我的像素位置的位置为[x,y] = find(bw2 == 0(;然后我如何删除它,然后填充原始背景
这是我的代码
[x, y] = find(Bw2 == 0);
[row, colo, z]=size(RGB); %size of rgb image
for i=1:row
for j=1:colo
if any(i==x) %if the row of rgb image is the same of pixel location row
if any(j==y(i==x)) %if the colos of rgb image is the same of pixel loca colo
Free_image= imfill(RGB,i,j);
end
end
end
end
我猜想BW2是与RGB相同的二进制掩码(没有第三维(。我也猜想您想用固定的背景颜色替换RGB中的所有像素,如果BW2中的相应像素为零。
如果是这样,您可以这样做:
bg_color = [0.5 0.5 0.5]; % this is gray, but can be changed to anything
sz = size(RGB);
numPix = sz(1) * sz(2);
indx = find(Bw2 == 0);
RGB(indx) = bg_color(1);
RGB(indx + numPix) = bg_color(2);
RGB(indx + numPix*2) = bg_color(3);
