有人可以帮助我使用此代码吗?它不会将黑色椭圆更改为白色.非常感谢:]]

Can anybody help me please with this code? it doesn't change the black ellipses to white.Thanks alot :]]

I = imread('untitled4.bmp');
Ibw = im2bw(I);
CC = bwconncomp(Ibw); %Ibw is my binary image
stats = regionprops(CC,'pixellist');

% pass all over the stats
for i=1:length(stats),
size = length(stats(i).PixelList);
% check only the relevant stats (the black ellipses)
if size >150 && size < 600
    % fill the black pixel by white
    x = round(mean(stats(i).PixelList(:,2)));
    y = round(mean(stats(i).PixelList(:,1)));
    Ibw = imfill(Ibw, [x, y]);
end;
end;

imshow(Ibw);

推荐答案

如果您的图像都是黑白的，并且您拥有图像处理工具包，那么您将需要以下内容: http://www.mathworks.co.uk/help/toolbox /images/ref/imfill.html

If your images are all black&white, and you have the image processing toolkit, then this looks like what you need:http://www.mathworks.co.uk/help/toolbox/images/ref/imfill.html

类似的东西:

imfill(image, [startX, startY])

其中startX，startY是您要填充的区域中的像素.

where startX, startY is a pixel in the area that you want to fill.
