SOFC Combustor Flame Image Enhancement Method Based on Wavelet Fusion
When the solid oxide fuel cell system is under full power operation for some reason,the combustion chamber will conduct insufficient combustion.The flame image will have high brightness and low contrast,which is adverse to image feature ex-traction and system analysis.To solve this problem,a flame image enhancement method of solid oxide fuel cell combustion chamber based on wavelet fusion is proposed.Firstly,the perceptually inspired variational framework is applied to enhance the contrast of the color mixing region and realize the image pre-enhancement.Then,the proposed detail preserving module is utilized for secondary image enhancement.Finally,the wavelet fusion method is applied to fuse the enhanced images to obtain the final image.The experi-mental results show that compared with the traditional methods,the proposed method can effectively preserve the details of the im-age and significantly enhance the image contrast to improve the image quality.
