1. One or more computer-readable media comprising computer-executable instructions for generating a normalized image lacking atmospheric effects present in an original image from which the normalized image is generated, the computer-executable instructions performing steps comprising: receiving the original image and original image metadata associated with the original image; selecting a subsection of the original image; determining, with reference to the original image metadata, a distance between an image capture device that generated the original image and an object represented by the selected subsection of the original image; determining, with reference to the original image metadata, an angle between the image capture device that generated the original image and the object represented by the selected subsection of the original image; generating a directional transmission coefficient, associated with the selected subsection, with the determined distance and the determined angle; modifying, to remove the atmospheric effects, the selected subsection of the original image, the modifying being performed with reference to the generated directional transmission coefficient that is associated with the selected subsection; and generating the normalized image with the modified selected subsection.
