Hi,

I want to compare two images and want to plot or remove the unmatched objects found. I was using ORB to find matches between two images, But how can I plot and show the unmatched one.

Many ways to do this, but the simple one is to use the void absdiff(InputArray src1, InputArray src2, OutputArray dst) function.

Calculates the per-element absolute difference between two arrays or between an array and a scalar.

Parameters:

  • src1 โ€“ first input array or a scalar.
  • src2 โ€“ second input array or a scalar.
  • dst โ€“ output array that has the same size and type as input arrays.
