Fast Automatic Visibility Optimization for Thermal Synthetic Aperture Visualization

نویسندگان

چکیده

In this article, we describe and validate the first fully automatic parameter optimization for thermal synthetic aperture visualization. It replaces previous manual exploration of space, which is time consuming error prone. We prove that visibility targets in integral images proportional to variance targets' image. Since invariant occlusion it represents a suitable objective function optimization. Our findings have potential enable autonomous search recuse operations with camera drones.

Multiple-Layer Visibility Propagation-Based Synthetic Aperture Imaging through Occlusion

Heavy occlusions in cluttered scenes impose significant challenges to many computer vision applications. Recent light field imaging systems provide new see-through capabilities through synthetic aperture imaging (SAI) to overcome the occlusion problem. Existing synthetic aperture imaging methods, however, emulate focusing at a specific depth layer, but are incapable of producing an all-in-focus...

an automatic algorithm based on angular histogram for corregistartion of synthetic aperture radar images

coregistration of optical and radar imageries is a major pre-processing step in many remote sensing applications including change detection and interferometric processing. specially, the coregistration faced more difficulties in radar imageries due to the high noise level and intense spatial-temporal decorrelation. hence, non-automatic coregistration methods are much more time consuming and ine...

Support Vector Machines For Synthetic Aperture Radar Automatic Target Recognition

Algorithms that produce classifiers with large margins, such as support vector machines (SVMs), AdaBoost, etc. are receiving more and more attention in the literature. This paper presents a real application of SVMs for synthetic aperture radar automatic target recognition (SAR/ATR) and compares the result with conventional classifiers. The SVMs are tested for classification both in closed and o...

Adaptive Boosting for Synthetic Aperture Radar Automatic Target Recognition

We propose a novel automatic target recognition (ATR) system for classification of three types of ground vehicles in the MSTAR public release database. First, MSTAR image chips are represented as fine and raw feature vectors, where raw features compensate for the target pose estimation error that corrupts fine image features. Then, the chips are classified by using the adaptive boosting (AdaBoo...

A fast autofocus algorithm for synthetic aperture radar processing

Synthetic Aperture Radar ( S A R ) has become a valuable instrument with applications in reconnaissance and remote sensing. High resolution SAR imaging requires the motion of the radar platform to be known very accurately. Otherwise phase errors are induced in the processing of the raw S A R data, and bad focusing results. In particular, a constant error in the measured along track velocity or ...
