Early tumor detection is a key factor in reducing breast cancer mortality. Screening mammography is the most widely available method for early cancer detection. However, the large amount of images to be read at each radiological session stress the radiologist ability to process each case with uniform attention. Computer aided detection (CADe) systems can improve tumor detection rate;but the current efficiency of these systems is not adequate and the correct interpretation of CADe outputs requires more time from the experts. Computer aided diagnosis systems (CADx) are being designed to improve cancer diagnosis accuracy and reduce radiological workload;but the efficiency CADx in screening mammography is not yet adequate for clinical use. Our hypothesis is that CADx sensitivity for mammography applications can be enhanced by considering the natural symmetry between the right and left breast. The primary objective of this work is to evaluate co-registration algorithms for the accurate alignment of the left to right breast for CADx applications. Three different set of registrations algorithms were tested: One based on B-Spline deformable transformations and two based on Demon's free form deformations. A set of mammograms was artificially altered to create a ground truth set of 132 images for the evaluation of the registration efficiency. The registration accuracy was visually inspected and quantitatively evaluated using mean square error, mutual information and correlation metrics. The results indicated that the B-Spline deformable registration outperforms Demon's for the task of registering mammography images.

The digital image processing of uncooled LWIR thermal detectors is one of the main steps in the research and development of thermal cameras. The study of this technology is a strategic issue for military and civil areas, considering that thermal imaging equipment have dual application. This paper aims to design and develop a pipeline of all processing steps required to obtain high performance images with low noise and high contrast. In addition to the digital processing algorithms, this paper presents some results of electro-optical characterization on the assembled system, indicating the main figures of merit that guide the study of this technology.

The interpretation of IR images depends on radiative properties of observed objects and surrounding scenery. Skills and experience of an observer itself are also of great importance. The solution to improve the effectiveness of observation is utilization of algorithm of image enhancing capable to improve the image quality and the same effectiveness of object detection. The paper presents results of testing the hardware implementation of IR image enhancing algorithm based on histogram processing. Main issue in hardware implementation of complex procedures for image enhancing algorithms is high computational cost. As a result implementation of complex algorithms using general purpose processors and software usually does not bring satisfactory results. Because of high efficiency requirements and the need of parallel operation, the ALTERA's EP2C35F672 FPGA device was used. It provides sufficient processing speed combined with relatively low power consumption. A digital image processing and control module was designed and constructed around two main integrated circuits: a FPGA device and a microcontroller. Programmable FPGA device performs image data processing operations which requires considerable computing power. It also generates the control signals for array readout, performs NUC correction and bad pixel mapping, generates the control signals for display module and finally executes complex image processing algorithms. Implemented adaptive algorithm is based on plateau histogram equalization. Tests were performed on real IR images of different types of objects registered in different spectral bands. The simulations and laboratory experiments proved the correct operation of the designed system in executing the sophisticated image enhancement.

An explicit way of facilitating approach and landing operations of fixed-wing aircraft in degraded visual environments is presenting a coherent image of the designated runway via vision systems and hence increasing the situational awareness of the flight crew. Combined vision systems, in general, aim to provide a clear view of the aircraft exterior to the pilots using information from databases and imaging sensors. This study presents a novel method that consists of image-processing and tracking algorithms, which utilize information from navigation systems and databases along with the images from daylight and infrared cameras, for the recognition and tracking of the designated runway through the approach and landing operation. Video data simulating the straight-in approach of an aircraft from an altitude of 5000 ft down to 100 ft is synthetically generated by a COTS tool. A diverse set of atmospheric conditions such as fog and low light levels are simulated in these videos. Detection and false alarm rates are used as the primary performance metrics. The results are presented in a format where the performance metrics are compared against the altitude of the aircraft. Depending on the visual environment and the source of the video, the performance metrics reach up to 98% for DR and down to 5% for FAR.

Rotary wing aircraft continue to experience mishaps caused by the loss of visual situational awareness and spatial disorientation due to brownout or whiteout in dusty, sandy or snowy conditions as the downwash of the rotor blades creates obscurant clouds that completely engulf the helicopter during approaches to land. BAE systems has developed a "see-through" brownout landing aid system technology (BLAST) based on a small and light weight 94GHz radar with proven ability to penetrate dust, coupled with proprietary antenna tracking, signal processing and digital terrain morphing algorithms to produce a cognitive real-time 3D synthetic image of the ground and proximate surface hazards in and around the landing zone. A series of ground and flight tests have been conducted at the United States Army's Yuma Proving Ground in Arizona that reflect operational scenarios in relevant environments to progressively mature the technology. A description of the BLAST solution developed by BAE systems and results from recent flight tests is provided.

The development of modern imaging and non-imaging infrared missile signal processing and countermeasure techniques strongly relies on high quality simulated imagery of target and countermeasure signatures. Likewise, the development of an effective countermeasure technique or system for aircraft self-protection requires accurate missile behaviour modelling. The development of these algorithms and protocols can be done most effectively in an accurate infrared imaging simulation. This paper investigates the requirements for such a simulation system, supporting the evaluation of the missile behaviour in the missile-aircraft engagement scenario. The development and evaluation of target detection and tracking algorithms, or countermeasure systems, requires a comprehensive simulation environment where thousands of missile flights can be simulated, covering a wide variety of scenarios and signature conditions. The missile seeker algorithms generally detect and classify targets based on intensity, spatial and dynamic characteristics. The key considerations identified for such an imaging infrared simulation system are: 1) radiometric accuracy in all spectral bands, i.e. sunlight and thermal radiance to provide correct colour ratios;2) accurate emitting source surface temperature behaviour, be it by aerodynamic or thermodynamic heating;3) high fidelity geo-metrical and spatial texture modelling to provide shape of targets and countermeasures;4) true dynamics and kinematic behaviour in six degrees of freedom;5) detailed modelling of signatures and backgrounds;6) accurate atmospheric transmittance and path radiance models;7) realistic rendering of the scene image in radiometric, spatial and temporal terms;and 8) comprehensive sensor modelling to account for primary and second order imaging effects. This paper briefly analyses the broader framework of requirements for an imaging simulation system, in the 0.4 to 14 mu m spectral bands. An existing imaging simulation system, OSSIM,

The image quality of today's state-of-the-art IR objective lenses is constantly improving while at the same time the market for thermography and vision grows strongly. Because of increasing demands on the quality of IR optics and increasing production volumes, the standards for image quality testing increase and tests need to be performed in shorter time. Most high-precision MTF testing equipment for the IR spectral bands in use today relies on the scanning slit method that scans a 1D detector over a pattern in the image generated by the lens under test, followed by image analysis to extract performance parameters. The disadvantages of this approach are that it is relatively slow, it requires highly trained operators for aligning the sample and the number of parameters that can be extracted is limited. In this paper we present lessons learned from the R&D process on using focal plane array (FPA) sensors for testing of long-wave IR (LWIR, 8-12 mu m) optics. Factors that need to be taken into account when switching from scanning slit to FPAs are e.g.: the thermal background from the environment, the low scene contrast in the LWIR, the need for advanced image processing algorithms to pre-process camera images for analysis and camera artifacts. Finally, we discuss 2 measurement systems for LWIR lens characterization that we recently developed with different target applications: 1) A fully automated system suitable for production testing and metrology that uses uncooled microbolometer cameras to automatically measure MTF (on-axis and at several off-axis positions) and parameters like EFL, FFL, autofocus curves, image plane tilt, etc. for LWIR objectives with an EFL between 1 and 12mm. The measurement cycle time for one sample is typically between 6 and 8s. 2) A high-precision research-grade system using again an uncooled LWIR camera as detector, that is very simple to align and operate. A wide range of lens parameters (MTF, EFL, astigmatism, distortion, etc.) can be easi

Contemporary infrared detector arrays suffers from technological imprecision which causes that the response to uniform radiation results in nonuniform image with superimposed fixed pattern noise (FPN). In order to compensate this noise there is a need to evaluate detectors characteristics like responsivity and offset of every detector in array. In article the method of determining the responsivity of detectors in a microbolometer array is described. In the method geometrical and optical parameters of the detector array and the measurement system are taken into account. A special test bench was constructed and is consisting of: two precise surface black bodies, aperture limiter, an electronic interface for data acquisition and software for measurement and correction of results with optical parameters of the measuring stand taken into account. Constructed aperture limiter enables evaluation of optical paths in measurement stand with equivalent relative aperture F# from 0.5 to 16.1 In order to evaluate the impact of optical path to radiation distribution in the measurement system, special radiation model was elaborated and evaluated in Zemax software. Incident radiation intensity distribution on the detector surface was calculated using Monte-Carlo method for various parameters of the optical path in the measurement system. Calculated radiation maps were used to compensate radiation intensity nonuniformity of optical measurement system giving more precise responsivity evaluation of detector array parameters. The obtained values of voltage responsivity of the detectors in the array, can be used in algorithms like nonuniformity correction and radiometric calibration of the infrared camera. In article results of responsivity evaluation is presented for microbolometer infrared arrays from ULIS company (France).

A new universal low computational complexity algorithm for numerical reconstruction of holograms recorded in near diffraction zone is presented. The algorithm implements digital convolution in DCT domain, which makes it virtually insensitive to boundary effects. It can be used for reconstruction of holograms for arbitrary ratios of hologram size to the object-to-hologram distance and wavelength to camera pitch and allows image reconstruction in arbitrary scale.

We do colour image processing in an RGB-derived spherical space with colour attributes given by hue, colourfulness (as opposed to grayness and somewhat different from saturation) and lightness;we call it Runge space. This spherical space is as intuitive as more common spaces of the type hue-saturation-luminance (called here eta, Sigma, Lambda spaces), yet it avoids the continuity problems of the transformation (R, G, B) -> (eta, Sigma, Lambda) that result from normalizing the saturation by the luminance, or of having a geometrically nonhomogeneous space, when the saturation is left un-normalized. We give Matlab routines for the conversions between colour spaces RGB and Runge, and present applications of colour modification in Runge space.
