Color characteristics of computer monitors and similar display devices can significantly alter the way an image is perceived by the human eye. Modern cameras and software applications are able to create vibrant scenes and retain their original colorfulness through an embedded ICC[1] profile. Gamut differences between input and output mediums require color management techniques in order to preserve...
An unsolved problem in medical image analysis is validation of methods. In this paper we will focus on image registration and in particular on nonlinear image registration, which is one of the hardest analysis problems to validate. The paper covers currently used methods of validation, comparative challenges and public datasets, as well as some of our own work in this area.
Fast and efficient design space exploration is a critical requirement for designing computer systems, however, the growing complexity of hardware/software systems and significantly long run-times of detailed simulators often makes it challenging. Machine learning (ML) models have been proposed as popular alternatives that enable fast exploratory studies. The accuracy of any ML model depends heavily...
The early theoretical studies that presented conceptual definitions for the mapping of Quality of Experience (QoE) through Quality of Service (QoS), in an approach focused on Distributed Databases (DDBs), showed the directions to be threshed in a way to accomplish a hybrid DDBs' QoE-QoS set of evaluation criteria. That evaluation set being classified explicitly as partial, since QoE is a known multidimensional...
When performing the internal audit of computer equipment an important problem is to identify the elf (executable and linkable format) files stored on the investigated hard drive. To solve this problem, we propose a method of identification of unknown elf-ffles based on the metric classification algorithms. The method consists of three stages. On the first stage the preparation of the training sample...
Current opinion on undergraduate studies has led to a reformulation of teaching methodologies to base them not just on learning, but also on skills and competencies. In this approach, the teaching/learning process should accomplish both knowledge assimilation and skill development. Previous works demonstrated that a strategy that uses continuous evaluation is able to meet both objectives. However,...
Mild Cognitive Impairment (MCI) results in a noticeable decrease in cognitive abilities but does not interfere with regular daily functions. Some patients with MCI may be able to return to age-appropriate cognitive abilities, but some will progress to dementia. Clinical interviews, tests and measurements are used to identify and monitor cognitive decline. Timely detection of cognitive decline provides...
Efficient ways are needed to visualize the health status of a person and how the lifestyle, daily choices and health care actions are affecting it. Current systems lack a comprehensive interface for interaction and exploration of large and complex data and events affecting the data. Based on state-of-the-art data visualization techniques, we implemented and user tested a system that visualizes health...
A complete ontology does not contain all domain information yet may still meet the requirements. Evaluation of ontology is necessary to determine the quality. To evaluate the quality of an ontology, various criteria have been proposed. This paper is a tribute to the works done through comparative study with the goal of identifying overlaps and establishing relationship of the various criteria. A framework...
This paper proposes the standard specification of metric numbers and is intended to discuss the topic. The numbers combined with metric prefixes like the 2k for the year, or 2k2 for resistors inscription are popularly used. However, there exists no standard to guide the use of such numbers, and typical precision is limited to few digits, as in the E24 series used for electronic parts. Computational...
