چکیده

We have developed a performance evaluation laboratory (PE Lab) to assess automated technologies that fuse fragmentary, partial information about individuals’ activities to detect modeled terrorist threat individuals, groups, and events whose evidence traces are embedded in a background dominated by evidence from similarly modeled non-threat phenomena. We have developed the PE Lab’s main components–a test dataset generator and a hypothesis scorer–to address two key challenges of counter-terrorism threat detection performance evaluation: 2 Acquiring adequate test data to support systematic experimentation; and 2 Scoring structured hypotheses that reflect modeled threat objects’ attribute values and inter-relationships.

Performance characteristics of three automated immunoassays for thyroid hormones

Background: Since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. We performed an analytical evaluation of the new electrochemiluminescent immunoassay (ECLIA) for serum TSH, FT4 and T3 in the Elecsys 2010 immunoassay system and compared the resu...

Automated classification of pulmonary nodules through a retrospective analysis of conventional CT and two-phase PET images in patients undergoing biopsy

Objective(s): Positron emission tomography/computed tomography (PET/CT) examination is commonly used for the evaluation of pulmonary nodules since it provides both anatomical and functional information. However, given the dependence of this evaluation on physician’s subjective judgment, the results could be variable. The purpose of this study was to develop an automated scheme for the classific...

Novel Automated Method for Minirhizotron Image Analysis: Root Detection using Curvelet Transform

In this article a new method is introduced for distinguishing roots and background based on their digital curvelet transform in minirhizotron images. In the proposed method, the nonlinear mapping is applied on sub-band curvelet components followed by boundary detection using energy optimization concept. The curvelet transform has the excellent capability in detecting roots with different orient...

Transferring x-ray based automated threat detection between scanners with different energies and resolution

A significant obstacle to developing high performance Deep Learning algorithms for Automated Threat Detection (ATD) in security X-ray imagery, is the difficulty of obtaining large training datasets. In our previous work, we circumvented this problem for ATD in cargo containers, using Threat Image Projection and data augmentation. In this work, we investigate whether data scarcity for other moda...
