I have used connected component analysis algorithm to identify the connected components in an image and reduced those components.But,in some case I don't exactly extract the license plate region.How can I rectify it?I have attached my code and the image on which I apply the code.Please help me in rectifying it.
figure,subplot(2, 1, 1);
imshow(c);
if ndims(c) > 1
c = c(:,:,1); % Take red plane
end
%binaryImage = imbinarize(c);
% Get rid of anything touching the edge of the image
% because this will definitely not be a license plate.
c = imclearborder(c);
% Extract the biggest blobs
c = imclearborder(c);
mask2 = imfill(c, 'holes');
mask2 = bwareafilt(mask2, 1); % Take largest.
% Use it to mask original
c(~mask2) = false;
%figure,imshow(c);
subplot(2, 1, 2);
imshow(c);
