Correct identification of obstacles at the periphery of airports is an important issue to ensure safe takeoff, flight, and landing to aircrafts. This work is carried on as part of the obstacle risk assessment and risk mitigation operations in the aviation security framework. This paper presents a novel fully automatic remote sensing methodology for the detection, shape and signature extraction and...
Correct identification of obstacles at the periphery of airports is an important issue to secure the safety of takeoff, flight, and landing to aircrafts. This work is carried on as part of the obstacle risk assessment and risk mitigation operations in the aviation security context. Specifically, this paper presents a novel methodology to change detection (CD) in pairs of high resolution (HR) ortho-rectified...
In the context of automatic image processing, noise is often the hardest problem to cope with. This is, in particular, true for images corrupted by multiplicative speckle noise, such as synthetic aperture radar images. To tackle such an issue, this letter proposes a novel anisotropic diffusion filter that manages to simultaneously fulfill competing requirements: reduce noise on homogeneous regions,...
This paper presents an automatic pre-screening algorithm of SAR images of huge size (more than 20;000×20;000 pixels), which is capable to identifying extended infrastructures in an effective and computationally efficient way. The algorithm is tested on true one-look Cosmo-SkyMed SAR image data for target detection purposes on an airport scenario. Both visual and objective results are presented to...
