I have a final bounding box attributes and an Image. I need to assign a number to each bounding box from the top left side in a sequential order. I have an object detected image like this.
Now I need a numbered object detected image some this like this. (Number position and size is not an issue)
How can I do that?

Please attach you image and required things so that we can help you in a bit more effective manner.

Put the coordinates into a 2D array. sortrows() with either [1 2] or [2 1] depending upon whether the numbering priority is down ([1 2]) or across ([2 1]) . Afterwards, the row number will be the number to use for the bounding box.

It looks like the output image you got is correct. Is there still a problem?
Be careful with sorting things, otherwise it's possible things could get mismatched. If you sort some things, like bounding box locations and labels, then you need to sort everything else the same way, otherwise, you might have the area of box 4 (say) with the area of box 2 (as shown by test on the image).

RGB = insertText(I, newpositions(:,1:2), 1:size(newpositions,1), 'FontSize', 22, 'AnchorPoint' ,'LeftBottom');
