Accurate color reconstruction is crucial for many technologies such as digital photography and computer vision.In or-der to improve the color reconstruction effect of images,a weighted non local Laplace based method is proposed.During the process,Laplace pyramid technology was used to improve the illumination of the image,and then image color reconstruction technology was de-signed based on non local Laplace diffusion.In the experimental results,the average gradient value of the research method for 2 k res-olution images remained above 6.23;99％of the image color similarity index in the research method is below 1.0.The results indi-cate that the research method can be well applied in different resolution scenarios,and the results of image color reconstruction have better image details.The reconstructed images have better visual consistency,and can ensure better color quality during color recon-struction.The resulting image has better smoothness,which can effectively complete color reconstruction of the image and provide fea-sible technical solutions for image processing.
