Demonstration of adaptive camouflage for the soldier

With the increased threat from advanced sensor systems using several wavelength bands and sensor fusion, the requirements on camouflage increase. Consequently, in order to reduce the risk of EU soldiers being detected, identified and engaged, adaptive camouflage prototypes have been developed, implemented and demonstrated. Several active and...

Measuring the dynamics of camouflage in natural scenes using convolutional neural networks

Natural scenes are typically highly heterogeneous, making it difficult to assess camouflage effectiveness for moving objects since their local contrast varies with their momentary position. Camouflage performance is usually assessed through visual search and detection experiments involving human observers. However, such studies are time...

Hybrid simulation approaches to create realistic scenes for signature assessment

To create a complete virtual scene with sufficient fidelity so it can be used for signature/camouflage assessment turns out to be complicated. Small differences in scene parameters can have a huge impact on the outcome and parameters are often unknown, which makes comparison with real environments/scenes difficult. Instead of fully virtual...

Misleiding en signatuur-management land [signature management and deception]

Camouflage and deception have been used in conflicts throughout the ages. In this respect, the twenty-first century is no different. However, constantly changing operational contexts, coupled with the rapid pace of developments in platform and sensor technology, are creating a rapidly growing threat. This has led to an urgent need for...

The relation between visual search and visual conspicuity for moving targets

In order to assess camouflage and the role of movement under widely ranging (lighting, weather, background) conditions simulation techniques are highly useful. However, sufficient level of fidelity of the simulated scenes is required to draw conclusions. Here, live recordings were obtained of moving soldiers and simulations of similar scenes...

Adaptive camouflage of moving objects

Targets that are well camouflaged under static conditions are often easily detected as soon as they start moving. We investigated and evaluated ways to design camouflage that dynamically adapts to the background and conceals the target while taking the variation in potential viewing directions into account. In a human observer experiment...

Demonstrator of adaptive visual camouflage based on LEDs

Within the EDA funded project ACAMSII, "Adaptive camouflage for the soldier", a future soldier system is being developed and implemented that provides adaptive camouflage against all relevant sensor threats, ranging from visible to thermal and radar. To provide adaptive camouflage in the visible domain LEDs are integrated in the clothing. A...

Adversarial patch camouflage against aerial detection

Adaptive camouflage of moving targets

Targets that are well camouflaged under static conditions are often easily detected as soon as they start moving. We investigated and evaluated ways to design camouflage that dynamically adapts to the background and conceals the target while taking the variation in potential viewing directions into account. In a human observer experiment...

Review of camouflage assessment techniques

In military operations signature reduction techniques such as camouflage nets, low-emissive paints, and camouflage patterns are typically deployed to optimize the survivability of high value assets by minimizing their detectability. Various methods have been developed to assess the effectiveness of these camouflage measures. There are three main...

Review of camouflage assessment techniques: presentation

Urban camouflage assessment through visual search and computational saliency

We present a new method to derive a multiscale urban camouflage pattern from a given set of background image samples. We applied this method to design a camouflage pattern for a given (semi-arid) urban environment. We performed a human visual search experiment and a computational evaluation study to assess the effectiveness of this multiscale...

Design and evaluation of (urban) camouflage

An international group consisting of several NATO nations participated in a trial in which urban camouflage was developed and compared. First, photographs were taken in and around a small town (arid climate). Next, the different groups derived urban camouflage patterns from these photographs. We applied our method for deriving a camouflage...

Guidelines for Camouflage Assessment Using Observers

The objective of SCI-095 was to advance alternative techniques for determining the camouflage effectiveness of military systems reliably at reduced cost. SCI-095 produced “Guidelines for Camouflage Assessment Using Observers” which is a standardized methodology for observerbased tests and statistical analysis. A comparative trial concluded that...

Experimental evaluation of thermal camouflage effectiveness

The detectability of a target in the infrared spectral region is determined by differences between the radiative signatures of the target and the local background. This implies that both, the difference in surface temperature and emissivity ΔT resp. Δε and the distribution of these differences over the target area and the background, are of...
