This paper proposes a new invariant feature-space system based in the log-polar image representation and SelfOrganizing Maps (SOMs). The image representation used, which is inspired by the structure of the human retina, allows data reduction and helps recognize image contents at different scales and orientations. Each object class is represented by a single prototype image, thus allowing classe...

Navigational systems performing real-time tasks involve many image related procedures, such as: acquisition, processing, and information extraction. Various components of these procedures consist of mathematical transformations that can be implemented optically. By using specially designed lenses these transformations can be provided at image acquisition time, and therefore, speed up execution ...

Over last years, the diffeomorphic image registration algorithms have been successfully introduced into the field of the medical image analysis. At the same time, the particular usability of these techniques, in majority derived from the solid mathematical background, has been only quantitatively explored for the limited applications such as longitudinal studies on treatment quality, or disease...

Logs contain valuable information about the runtime behaviors of software systems. Thus, practitioners rely on logs for various tasks such as debugging, system comprehension, and anomaly detection. However, are difficult to analyze due their unstructured nature large size. In this paper, we propose a novel approach called <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http:...
