Fill in boundaries in Image
显示 更早的评论
How can I fill in the red regions in the image below given by:
%DrawRegions from Binary onto raw image:
labeledImage = bwlabel(Back, 8); % Label each blob so we can make measurements of it
blobMeasurements = regionprops(labeledImage, ROI, 'all'); %ROI is original image
numberOfBlobs = size(blobMeasurements, 1);
hold on;
boundaries = bwboundaries(Back);
numberOfBoundaries = size(boundaries);
subplot(4,5,[1,2,6,7])
hold on
for k = 1 : numberOfBoundaries
thisBoundary = boundaries{k};
plot(thisBoundary(:,2), thisBoundary(:,1), 'r.', 'LineWidth', 1);
end
hold off;
i.e. the red boundaries in the image.

What do you want to fill it with?
And a side question, the red region apparently comes from the bwlabel of Back. Isn't Back already filled red region then?

Mohammad's code worked for Jason. Doesn't it work for you? If not, post your image and code in a new question.

Ok, but the red lines is pretty much the boundary of the regions in the binary image stored in the variable called back, right?
If that is the case, and assuming your raw-image is a one layer gray scale image, i.e. size of raw_image is NxMx1 (based on your past posts then 101x101) then here is what you should do
RGB(:,:,1)=min(double(Back)+double(raw_image)./max(double(raw_image(:))),1);
RGB(:,:,2)=double(raw_image)./max(double(raw_image(:)));
RGB(:,:,3)=double(raw_image)./max(double(raw_image(:)));
Of course Back needs to be the same size as of raw_image.
