Hello, I am facing an issue with saving my image after cropping it. This is my image
But when i save my image i am getting this,
Could anyone tell me how I can save the image without the extra white area in the background? Thank you
edit: Here is my code
img = rgb2gray(imread('C:\Users\Shruthi\Desktop\project\A data\lazy.jpg'));
erodeImg = imerode(img,strel('disk',3));
imshow(erodeImg,[])
BW = bwlabel(erodeImg);
imshow(BW,[])
img = bwareaopen(BW,30);
pause(1)
[L Ne]=bwlabel(img);
regProp=regionprops(L,'BoundingBox');
hold on
for n=1:size(regProp,1)
rectangle('Position',regProp(n).BoundingBox,'EdgeColor','r','LineWidth',2)
end
figure;
imshow(img);
hold off
pause (1)
close
for n=1:Ne
[r,c] = find(L==n);
n1=img(min(r):max(r),min(c):max(c));
figure;
imshow(~n1);
saveas(figure(n),fullfile('C:\Users\Shruthi\Desktop\project\A data\SegmentedCharacters',['figure' num2str(n) '.jpg']));
end
and here is my image :

You would have to show us the code you're using for us to tell you what you're doing wrong.

You're not saving the images per say, but saving the content of the figure window. Replace your saveas line with:
imwrite(~n1, fullfile('C:\Users\Shruthi\Desktop\project\A data\SegmentedCharacters', sprintf('image%d.jpg', n)));
