Abstract: The color, brightness distribution and shape pattern of flames vary under different working conditions, thus showing multi-modality. In addition, the background environment is highly coupled with the foreground image because of the reflection, aerosol, dust and other interferences. Traditional segmentation algorithms cannot ensure accuracy under a variety of conditions. A method of flame image segmentation based on multivariate image analysis and expert knowledge is proposed. The principal component analysis method was used to reduce the dimension of images and to construct the scatter plot of the scores, so as to obtain the regions of flame segmentation. The method was applied to the video monitoring of the production of fused magnesium furnace, which verified the performance of this method.

Key words: image segmentation, dynamic flame, multivariate image analysis, fused magnesium furnace process, video monitoring
