Centerline detection from the binary image.
显示 更早的评论
I have multiple images taken of the same object.
However, as in the example below, not all objects are located in the center.
I want to identify central axis of the object(based on the standard of ensuring that the length of the light blue arrows is the same as shown in the image below) and indicate the center line and crop the image based on this.
I think I can do the crop itself as long as I know the index of the center line.
It would be very helpful if you could tell me where to start.
Thank you!

What I'd do is to find the rows where you have two blobs, instead of 0 or 1. Then for those, log the left edge and the right edge. Then take the average of them after you've scanned every row. Let me know if you can't figure it out.

I didn't detect rectangulars, but would this work for you?
img_orig = imread('image.png');
img = imbinarize(img_orig);
[~,c] = find(img(:,:,1) == 1);
figure;
imshow(img_orig); hold on;
line(ones(1,2) * mean(c), [0, size(img,1)],'color','r', 'linewidth',2)
