The orthogonal multi-resolution analysis was applied to the digital imaging photographs of lobed mixing jets for revealing the time varying turbulent structures of various scales. The image components of five different broad scales are obtained, and each image components can provide information on the multi-scale turbulent structures. The complex vortical structures of various scales were clearly extracted and visualized at different instances.
