Abnormal running of the motor would cause its temperature changing. The pixel gray values of a infrared image can reflect the relative temperature levels of the object. It is a good diagnosis method to obtain the motor temperature levels via the luminance variation of the motor infrared image. But the infrared images obtained by the IR imaging sensor are low contrast
and serious noisy
therefore
it is necessary to enhance the IR images. Based on wavelet and weighted filtering
a novel enhancement method is proposed in this paper
this algorithm could retain high and low frequency information well. The results show that this enhancement algorithm has excellent image enhancing function and visual effect.
