Resolution comparison using two circles with a radius of 10 mm, generated simultaneously with varying center-to-center distances. The distances range from 1 mm (bottom row) to -4 mm (top row, indicating overlap), increasing by 1 mm per row. The second row from the bottom shows the circles touching at their outer edges. Images were captured with 1, 3, 9, and 24 frames, both before and after applying the Digital Twin process.
