Aerial and satellite images often contain haze. The presence of haze reduces image contrast and makes
visual examination of images difficult. As a preprocessing operation to image registration and image
fusion, there is a need to remove haze from images and increase image contrast. A software developed by
Image Registration and Fusion Systems removes most haze from images. Haze is removed automatically
or interactively. Interactive haze removal is achieved with the motion of the mouse. An example of
automatic haze removal by this software is given in Fig. 1. Fig. 1a is the original hazy image and Fig. 1b is
the image after haze removal. Details previously not visible in the hazy image are now visible in the
enhanced image. Additional examples of haze removal by this software are given in Figs. 2 - 4.

The Haze Removal software reads in a hazy image and displays it in two windows side by side. The left
window always shows the original hazy image and the right window shows the haze removed image.
Side-by-side viewing enables comparison of images before and after haze removal. A snapshot of the
image viewer for this software is shown below. For very large images, the images are scaled down to fit the
screen. However, the user is allowed to pan and zoom the image to view local details. This is also shown
below. The pan and zoom operations of the two windows are synchronized to facilitate viewing of the same
scene areas before and after haze removal.
