Development of an automated microscopic imaging system for TB screening

This paper proposes an automated microscopic imaging system (MIS) for TB screening. Mainly, the system consists of integrated hardware and software components for sputum smear slides feeding, controlling and carrying out microscopic and image processing functions of the system. The MIS is used to distinguish TB positive and negative cases. The hardware system and controlling mechanism of MIS are discussed. Algorithms for focusing of the microscope and image processing are presented. Experiments are carried out to evaluate the proposed automated microscopic imaging system.
