Abstract. We present an imaging, image processing, and image analysis framework for facilitating the separation
of flow and chemistry effects on local flame front structures. Image data of combustion processes are obtained
by a novel technique that combines simultaneous measurements of distribution evolutions of OH radicals and of
instantaneous velocity fields in turbulent flames. High-speed planar laser induced fluorescence (PLIF) of OH radicals
is used to track the response of the flame front to the turbulent flow field. Instantaneous velocity field measurements
are simultaneously performed using particle image velocimetry (PIV). Image analysis methods are developed to
process the experimentally captured data for the quantitative study of turbulence/chemistry interactions. The flame
image sequences are smoothed using nonlinear diffusion filtering and flame boundary contours are automatically
