A 30s video of the face, suffering fluctuations in illumination, and corrupted by facial expressions.
We can count the number of bacilli in ZN-stained sputum smears automatically, irrespective of their shape, size, and the presence of staining artifacts.
This assists the technician: manual counting - as per protocol - is tedious and error-prone.
