Flame Image Pre-processing Research for Coal-fired Utility Boiler

摘要

Aiming at the problems of coal-fired utility boiler, such as flame fluttering, isolated noise, and lacking adequate contrast in flame image. To extract characteristics of flame image for combustion mode identify, the mean of multi-image, median filter, subsection gray linear transformation, binariazation, isolated spots elimination and filling in blanks were operated. The result shows that the flame segmentation from background is effective.
