| Abstract: | Industrial X-ray battery images have shortcomings such as low contrast,obvious noise effect,and poor visual effects.The paper proposes multi-scale Retinex and homomorphic filtering algorithm to enhance the X-ray battery image.Reflection component is obtained by using Gaussian filter in multi-scale Retinex algorithm to estimate illumination component.The improved histogram equalization method is used to process the illumination component to enhance the contrast of the image.The reflection component is enhanced with improved butterworth high-pass filter,the reflected component is fused in the same proportion with the illumination component and then enhanded images can be obtained by the improved homomorphic filtering.The effectiveness of the proposed algorithm is evaluated by objective methods.The results show that the proposed algorithm has a good image enhancement effect and more detailes can be seen by it. |
