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...

The aim of the present study was to investigate how display density affects attentional guidance in heterogeneous search displays. In Experiment 1 we presented observers with heterogeneous sparse and dense search displays which were adaptively changed over the course of the experiment using genetic algorithms. We generated random displays, and...

We introduce a multiscale image fusion scheme based on guided filtering. Guided filtering can effectively reduce noise while preserving detail boundaries. When applied in an iterative mode, guided filtering selectively eliminates small scale details while restoring larger scale edges. The proposed multi-scale image fusion scheme achieves optimal...

The defense and security community have to cope with threats in complex environments that are merged in the scene context. The aim of this study is to investigate if fusion of Gated Viewer images with traditional thermal IR images provides a solution for threat recognition (with context understanding) in complex environments; and if contextual...

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...

Defense and security surveillance scenarios typically involve the detection and classification of targets in complex and dynamic backgrounds. Imaging systems deployed for this purpose should therefore provide imagery that enables optimal simultaneous recognition of both targets and their context. Here we investigate the recognition of semi...

Human actions are spatio-temporal patterns. A popular representation is to describe the action by features at interest points. Because the interest point detection and feature description are generic processes, they are not tuned to discriminate one particular action from the other. In this paper we propose a saliency measure for each individual...

The objective of image fusion is to represent relevant information from multiple individual images in a single image. Some fusion methods may represent important visual information more distinctively than others, thereby conveying it more efficiently to the human observer. Here, we propose to rank order images fused by different methods...

The predictions of 13 computational bottom-up saliency models and a newly introduced Multiscale Contrast Conspicuity (MCC) metric are compared with human visual conspicuity measurements. The agreement between human visual conspicuity estimates and model saliency predictions is quantified through their rank order correlation. The maximum of the...

We present a new Tri-band Color Low-light Observation (TRICLOBS) system The TRICLOBS is anall-day all-weather surveillance and navigation tool. Its sensor suite consists of two digital image intensifiers and an uncooled longwave infrared microbolometer. This sensor suite registers the visual, near-infrared and longwave infrared bands of the...

We tested the saliency of a single vibrotractile target (T) among 2 to 7 nontargets (N), presented by 8 tactors that were equally distributed over a horizontal band around the torso. Targets and nontargets had different pulse duration, but the same activation period and no onset asynchrony. T-N similarity was varied by changing the difference...
