A New Edge Detection Algorithm for Flame Image Processing

Digital image processing is playing an increasingly important part in imaging based flame monitoring systems. A crucial step in flame image processing is to detect the flame edge, a dividing boundary between the area where there is thermo-chemical reaction and those without. The determination of flame edges is a precursor to flame image processing and measurement of flame parameters. Several known edge detection methods have been tested to identify flame edges but the results achieved are disappointing. As a result of recent work in feature analysis of flame images, a novel flame edge detection method has been developed, which can detect the flame edges effectively and efficiently.
