Hello,

I have a binary image on wich I detect rectangles that have the sieze of 164*20 pix each one and should be full of '1' (no black pixel inside).

I have the cordinates (x,y) of the top left corner of each rectangle.

I want to group my rectangles so that the distance on the width should be less than 82px and on the heigh should be less than 10px.

Please find example below:

Here my full image with all the detected rectangles:

Here a part of my image:

Here what I expected (in blue) when groupin the rectangles in this part

Remark:

When grouping, there is no problem if some black pixels are taken.

Regards,

Mehdi
