A method of low light image enhancement without reference based on visual communication technology
In order to optimize the low-light image enhancement effect,a non-reference low-light image enhance-ment method based on visual communication is proposed.The proposed method reconstructs the low-light image through panoramic imaging technology,uses computer principles to simulate the optical imaging system,and introduces multifractal method and semi-soft threshold exponential attenuation method to remove the noise on the reconstructed image.The best transmittance in the process of image enhancement is calculated by the light and dark dual-channel coefficient,and the low-light image is enhanced by this transmittance.The experimental results show that the recon-structed image is complete,the overall quality of the image is high,and the SIMM value is close to 1.The image de-noising is achieved without affecting the image definition.The enhancement effect on the low-light image is obvious,avoiding the image exposure during the enhancement process,and achieving the complete retention of image details.
