of the three models are above 0.9379, indicating that the established quantitative models have high accuracy, reliability and good prediction ability.Finally, the quantitative models have been successfully applied in the determination of three components of B-vitamin complex tablets produced by different manufacturers.It could be seen that the Tchebichef image moment method can solve the signal overlap and interference of multi-target components and provides an important basis for the simultaneous quantitative analysis of multi-components in complex systems.
