Abstract: Based on the traditional infrared enhancement method,a new weight-based infrared image details enhancement algorithm is proposed,which fully utilizes the histogram characteristics to enhance the contrast of infrared image while keeping the image details.In various complicated scenes with obvious temperature changes,the detail information can be guaranteed in the image while suppressing the background noise with this algorithm which has good enhancement and high real-time performance.After experimental verification,the target contrast is improved greatly,the target details is emerged effectively with this algorithm,and the signal-to-noise ratio is increased,which has good practicability.
