performing inverse discrete cosine transform on DL to obtain the fused image resL at a low resolution;
using a relationship between the resL image and multiple down-sampled images to obtain multiple corresponding ratio images, up-sampling the ratio images by m times, and performing a point multiplication operation between the up-sampled ratio images and inputted original images, and then fusing through corresponding mask images to obtain the panoramic image which is clear and has no color difference and brightness difference.
