I have an image like this

image description

Now I have the centroid of the bounding box and I want to sort them in row-wise order as in images 3 and 5 are changed.

How to solve it

I have used euclidian distance and python OpenCV

An original image is the image without bounding box nothing than that

I don't see a factory cv.CV_SORT_ASK in this format. You can loop arr.size() and push arr.get(i) to a standard array. Then arr.sort() on multiple factors.

Sort x/y coordinate on a generalized grid unit, i.e. 25%, 50%, to allow minor pixel differences. Also, perceptually, a second centroid 3% to the right but 300% larger could be promoted.
