Gradient method of objects edge detection on aerial photographs

Annotations languages:

We propose a method of objects edge detection on a digital aerial photograph, which may be realized in future automatic control systems in Air Forces for automatic data processing of airviews. Current method is based on a derivatives calculation of RGB image components at each point (pixel) and a decision-making about existence or absence an objects edge in consideration with threshold at a considered area.
