80 страниц. 2013 год. LAP Lambert Academic Publishing In this book, we propose an effective fog-free methodology for remove fog from input image. In our work, firstly, the original image is converted from RGB to YCbCr. Secondly, compute the intensity component of the YCbCr image and key observation of the all pixels of the image. Most local patches in fog-free outdoor images contain some pixels which have very low intensities in at least one color channel. Using this methodology with the fog image, we can directly estimate the local white balancing of the image, global white balancing of the image, median of the image and mean of the image.After getting all above details, we apply on original image and finally show the fog free image.
