Polymer insulators tend to fail because of the climatic and environmental conditions. The failure occurs when the surface of insulator is contaminated by sea salt or cement dust which lead to partial discharge (PD). Leakage currents will increase by PD that causes deterioration of insulation. To predict the insulation failures, an adaptive neurofuzzy inference system (ANFIS) method using initial color detection processes are proposed to estimate the leakage currents based on the polymer...

In recent years, cross spectral matching has been gaining attention in various biometric systems for identification and verification purposes. Cross spectral matching allows images taken under different electromagnetic spectrums to match each other. In cross spectral matching, one of the keys for successful matching is determined by the features used for representing an image. Therefore, the feature extraction step becomes an essential task. Researchers have improved matching accuracy by...

Emotional reactions are the best way to express human attitude and thermal imaging mainly used to utilize detection of temperature variations as in detecting spatial and temporal variation in the water status of grapevine. By merging the two facts this paper presents the Discrete Cosine Transform (DCT) with Local Entropy (LE) and Local Standard Deviation (LSD) features as an efficient filters for investigating human emotional state in thermal images. Two well known classifiers, K-Nearest...

A novel sensor is being developed for a new uncooled imager technology that is scalable to large formats (tens of mega pixels) which is greater than what is achieved by commercial micro-bolometer arrays. In this novel sensor, a liquid crystal transducer is used to change a long-wavelength infrared scene into a visible image that can be detected using a conventional visible imager. This approach has the potential for making a more flexible thermal sensor that can be optimized for a variety of...

We present a comparative study of face recognition performance with visible and thermal infrared imagery, emphasizing the influence of time-lapse between enrollment and testing images. Most previous research in this area, with few exceptions, focused on results obtained when enrollment and testing images were acquired in the same session. We show that the performance difference between visible and thermal recognition in a time-lapse scenario is smaller than previously believed, and in fact is...

In this work we have developed novel experimental platforms to understand the structure property relationship of molecular junctions. Specifically, we sought to investigate the feasibility of creation of organic-based thermoelectric energy conversion. Towards this goal, we first developed a picowatt-resolution calorimeter that is critical for characterizing thermal transport through molecular junctions (Sadat et al., Appl. Phys. Lett., 2011). Subsequently, we developed a novel thermal imaging...

For nighttime surveillance applications, acquisition of visible light imagery is impractical due to the lack of illumination. Thermal imaging, which acquires mid-wave infrared or long-wave infrared radiation naturally emitted by the human body, can be utilized in low light conditions to perform surveillance tasks. Identification of individuals captured by thermal imaging would significantly enhance nighttime intelligence gathering capabilities. However, government watch lists and databases...

This paper outlines a method to automatically detect targets from sets of pixel registered visual, thermal, and range images. The method uses operations specifically designed for the different kinds of images. It also introduces the morphological operation called erosion of strength n as a powerful tool for removal of spurious information. Good preliminary results obtained for detection support its suitability for application to the Automatic Target Recognition (ATR) problem.

This project is a research effort that helps define thermal infrared (IR) imaging as a diagnostic tool in early detection of breast cancer, which can be used as a complementary to traditional mammography. One of the popular methods for breast cancer detection is to make comparisons between contralateral images.

When thermal imaging sensors are used for automatic target detection and recognition of ground targets, the performance is often limited by the small thermal contrast between target and background. In comparison, polaimetric imaging is minimally dependent on the thermal characteristics of the target. Polarimetric data depends, instead, on the three-dimensional shape and surface properties of the target. Physics Innovations Inc. and Lockheed Martin Corp, have an ongoing program to develop...

A key problem for face recognition has been accurate identification under variable illumination conditions. Conventional video cameras sense reflected light so that image gray values are a product of both intrinsic skin reflectivity and external incident illumination, thus obfuscating the intrinsic reflectivity of skin. Thermal emission from skin, on the other hand, is an intrinsic measurement that can be isolated from external illumination. We examine the invariance of Long-Wave InfraRed...
