Computer-Aided Diagnosis (CAD) Conference at the SPIE Medical Imaging Symposium

Calcium burden determined in CT images acquired in lung cancer screening is a strong predictor of cardiovascular events (CVEs). This study investigated whether subjects undergoing such screening who are at risk of a CVE can be identified using automatic image analysis and subject characteristics. Moreover, the study examined whether these individuals can be identified using solely image information, or if a combination of image and subject data is needed. A set of 3559 male subjects undergoing Dutch-Belgian lung cancer screening trial was included. Low-dose non-ECG synchronized chest CT images acquired at baseline were analyzed (1834 scanned in the University Medical Center Groningen, 1725 in the University Medical Center Utrecht). Aortic and coronary calcifications were identified using previously developed automatic algorithms. A set of features describing number, volume and size distribution of the detected calcifications was computed. Age of the participants was extracted from image headers. Features describing participants' smoking status, smoking history and past CVEs were obtained. CVEs that occurred within three years after the imaging were used as outcome. Support vector machine classification was performed employing different feature sets using sets of only image features, or a combination of image and subject related characteristics. Classification based solely on the image features resulted in the area under the ROC curve (A(z)) of 0.69. A combination of image and subject features resulted in an A(z) of 0.71. The results demonstrate that subjects undergoing lung cancer screening who are at risk of CVE can be identified using automatic image analysis. Adding subject information slightly improved the performance.

Conference on Laser Power Beaming

Massively parallel algorithms and architectures for real-time wavefront control of a dense adaptive optic system (SELENE) are presented. We have already shown that the computation of a near optimal control algorithm for SELENE can be reduced to the solution of a discrete Poisson equation on a regular domain. Although this represents an optimal computation, due to the large size of the system and the high sampling rate requirement, the implementation of this control algorithm poses a computationally challenging problem since it demands a sustained computational throughput of the order of 10 GFlops. We develop a novel algorithm, designated as Fast Invariant Imbedding algorithm, which offers a massive degree of parallelism with simple communication and synchronization requirements. We also discuss two massively parallel, algorithmically specialized, architectures for low-cost and optimal implementation of the Fast Invariant Imbedding algorithm.

Medical Imaging 1997 Symposium - Image Processing

作者： Udupa, JK Odhner, D Tian, J Holland, G Axel, L Univ. of Pennsylvania Medical Ctr. (United States)

ISBN: (纸本)0819424455

In MR and CT angiography, clutter due to artifacts or nearby high-intensity structures, such as other uninteresting vessels and bone (in CT), prevents clear visualization of the vessel under investigation. In this paper, we offer an alternative to the manual editing that is commonly used to remove clutter. The method is automatic and requires the user to point at structures on a 3D MIP display. The method utilizes recently developed fuzzy connected object delineation algorithms to extract the vessels of interest. Since the resulting definition is nonbinary, it can be displayed via MIP or more sophisticated volume rendering.

A Rotating fan-beam scatterometer (RFSCAT), which provides a set of different incidence and azimuth angle combinations and wide continuous swath coverage, will be flown on the Chinese-French Oceanography Satellite (CFOSAT). In this paper, a pre-processing algorithm is developed to estimate the backscatter coefficient (sigma(0)) of RFSCAT, which includes the procedures of system distortion correction, thermal noise removal, internal signal calibration, and elimination of the observing geometry effects. The algorithm is then tested using the experimental data from an airborne campaign. The estimated s0 are consistent with Nscat-2 geophysical model function (GMF), indicating that the pre-processing chain acts well for RFSCAT.

Conference on Optical Tomography and Spectroscopy of Tissue X

In this work, synthetic time-domain data are generated as if it were collected with a state-of-the-art multi-view experimental optical scanner developed in our group for small animal imaging, and used in a tomographic image reconstruction algorithm. The collected data comprises full time-dependent optical signals leaving the biological medium and acquired all around the medium. The diffuse optical tomography (DOT) algorithm relies on the time-dependent parabolic simplified spherical harmonics (TD-pSP(N)) equations as the forward model to recover the 3D absorption and diffusion coefficient maps of the medium. The inverse problem is casted and solved as an iterative constrained optimization problem where an objective function determines the accuracy of the forward model predictions at each iteration. Time-dependent adjoint variables are introduced to accelerate the calculation of the gradient of the objective function. A three-dimensional case involving an absorption heterogeneity in a homogeneous medium is presented, reproducing practical situations encountered in our lab. The results support our hypothesis that accurate quantitative 3D maps of optical properties of biological tissues can be retrieved using intrinsic measurements obtained with our experimental scanner along with our DOT algorithm.

CONF ON OCEAN OPTICS 10

作者： PHILPOT, WD Cornell Univ. (United States)

ISBN: (纸本)0819403539

The usual goal of aircraft and satellite remote sensing is to extract information which is directly related to ground targets in spite of atmospheric degradation which often complicates target identification and classification. Empirical algorithms which attempt to characterize targets by their spectral shape (slope, curvature, etc.) have been successful under special conditions, but fail when spectral variations in the solar or atmospheric parameters overwhelm those of the target reflectance. It is possible to derive an algorithm based on derivatives of the radiative transfer equation. This makes it possible to define the conditions under which a derivative algorithm will be insensitive to atmospheric effects and allows estimation of expected errors. This paper describes the development of the "derivative ratio algorithm," based on derivatives of a simple radiative transfer equation. The limiting conditions of the algorithm are derived and demonstrated using examples of reflectance spectra of turbid water and an ash leaf.

As a result of an on-going IR&D effort, General Atronics Corporation (GAC) has developed effective algorithms for automatic acquisition, tracking, and recognition of multiple targets - broadly referred to as Automatic Target Recognition (ATR) - using passive sensors on board multiple distributed platforms. The goal of AIR is to either provide timely and accurate assistance to a human operator, who is the ultimate decision maker, or he totally autonomous in extracting the necessary information, its processing, and final decision making. Applications of this technology include Electro-Optical Fire Control Systems (EOFCS), Infrared Search and Track (IRST), Infrared Counter Measures (IRCM), Covert Aircraft Recovery and Tracking Systems (CARTS), Strategic Defense Initiative (SDI), Anti-Submarine Warfare (ASW), Battlefield Intelligence, and Security.

Conference on Image Processing - algorithms and Systems X and Parallel Processing for Imaging Applications II

作者： Herrmann, Enrico Makrushin, Andrey Dittmann, Jana Vielhauer, Claus Otto Von Guericke Univ Univ Pl 2 D-39106 Magdeburg Germany Univ Appl Sci Brandenburg Magdeburg Germany

In an attempt to further develop and evaluate the optical recognition systems for distinguishing between driver and front-seat passenger during their interactions with dual-view touch screen integrated to the automobile centre console, this work focuses on the enhancement of both image processing algorithms and experimental environment. In addition to the motion based forearm and hand segmentation and the texture based arm direction analysis, the adaptive boosting classifiers with Haar-like features have been engaged for the learning of driver's and passenger's hand patterns. The user discrimination system was completely reproduced in a laboratory, including passenger compartment with genuine dashboard, touch screen, camera and near-infrared lamps, so that different illumination conditions could be modeled. The new acquisition system allows automatic and unambiguous registration of all touch screen interactions and their synchronization with the video stream. This results in credible evaluation of the image processing routines. The adjustment of the camera position and the active infrared illumination made it possible to reduce the recognition error rates and to achieve superior discrimination performance compared to previous works.

ISBN: (纸本)0819428353

A compact (Camcorder size), ultrahigh-speed, grayscale optical correlator capable of using grayscale input and real-valued correlation filter is reported. The unique bipolar-amplitude correlation filter modulation capability has enabled the direct implementation of composite filter algorithm such as MACH [8]. The direct usage of grayscale input also eliminated the need of image preprocessing (e.g. Sober filtering used for binary optical correlator). System architecture of this grayscale optical correlator will be described. Experimental results obtained using optically implemented MACH filter, for the first time, will also be provided.
