摘要
Image fusion based on a modified method of frame averaging for noise removal by partly averaging over images having a smaller resolution than the desired resolution of the de-noised image. The set of images which are summed for averaging out noise consists of two subsets. The first set of images has a resolution (in terms of number of pixels) being smaller than the resolution of the images in the second set. The resolution of the images in the second set is the resolution of the ‘high-definition’ de-noised output image. The lower resolution images are up-sampled by scaling their pixel numbers to that desired output image. The gradation of the first set images is also adapted to avoid intensity saturation (flare) due to sommation. Image fusing is also done in fourier space using the high frequency components from the higher resolution images and the lower ones from the lower resolution images.
