It is very important to collect the information of enemy in modern war. If we can know how the enemy disposes their forces, then we can make a good decision and prevent the happening of worst situation. Recently, due to the fast and mature development of satellite technologies, the satellite scanning resolution has been uplifted higher. Moreover, the scanning range covering by satellites almost has no forbidden area. It can be easily applied for military purpose. In response to this need, a novel method is proposed to detect vehicles in satellite images.
There are many approaches presented to detect objects in satellite images. In this thesis, an edge-based approach is proposed using the Canny’s edge detection method to detect object’s edges in satellite images. Then, the related edge-map can be found from object’s edges. Simultaneously, original satellite images are also preprocessed to reduce some unwanted situations, and then use image processing techniques to find out the ROI (region of interest) which contains the vehicles. Finally, we can successfully detect all vehicles in satellite images from the edge-map together with the ROI image.
Experiments were conducted on various satellite images and the results show that our proposed method is feasible and effective in detecting vehicles presented in satellite images. Furthermore, we can utilize this approach to detect other objects in satellite images. |
