In the actual scanning process, the projection data is inevitably influenced by various noises, thus it affects the precision of reconstructed image, which brings certain troubles for subsequent image processing. In order to improve the quality of the image reconstruction, this paper proposes a new method of image reconstruction. Firstly, we use the wiener filtering to deal with the iteration result...
If we use the image haze removal of dark channel prior, we're prone to color distortion phenomenon for some large white bright area in the image. Aimed at these problems, this paper presents an image haze removal of wiener filtering based on dark channel prior. The algorithm is mainly to estimate the median function in the use of the media filtering method based on the dark channel, to make the media...
