Color Restoration of Aerial Photographs

Image restoration based on multiscale relationships of image structures

Aerial photographs sometimes suffer from artifacts caused by vignetting effects and changing topographic sun–canopy–sensor geometry. In this paper, we present an empirical image restoration method that is based on multiscale relationships of image structures. The fine-scale image structures depict tree crowns in a deciduous forest and serve as units in the restoration process. The color image i...

3D Modelling as a Tool for Landscape Restoration and Analysis

The region of North-west Bohemia has been influenced by the open cast mining for more than the last hundred years. During this period has the coal mining activity become very intense leaving huge change on the landscape. We may require the original landscape for many purposes (historical, landscape renewal). One of the ways how to reconstruct the original shape of the landscape is the usage of ...

Utilization of A S f P Photographs in the Study of Small Structures in Abu Rawssh and WIdi el NatrQn , Egypt

This paper deals with a study of geologic structures using 8 X enlargements of Apollo-Soyuz Test Project color photographs. The two study areas are Abu Rawdsh and Whdi el NatrQn; both are in the northern part of the Western Desert of Egypt. Because the structures are small, aerial photographs were studied and field checks were made to verify the findings from Apollo-Soyuz photographs. The Apoll...

Automatic Detection and Classification of Infestations of Crop Insect Pests and Diseases from Infrared Aerial Color Photographs

Automated Shadow Compensation in Color Aerial Images

In urban aerial images, shadows cast by culture features due to solar orientation are usually homogenous and among the darkest regions in images and they make the feature under them unrevealed. This paper presents automatic procedures for shadow detection and radiometric restoration of features under cast shadows in color aerial images for solving problems caused by cast shadows in digital imag...
