This paper presents a new formulation of the regularized image up-sampling problem that
incorporates models of the image acquisition and display processes. We give a new analytic …

This paper proposes a method to resample the signal against the angle by using the
acceleration signal of a gearbox. Firstly, the method is presented. Gear tooth pairs produce …

The main contribution of our approach is to apply the Hilbert-Huang Transform (which
consists of two parts:(a) Empirical Mode Decomposition (EMD), and (b) the Hilbert spectral …

We present an elastic registration algorithm for the alignment of biological images. Our
method combines and extends some of the best techniques available in the context of …

The objective of inter-subject registration of three-dimensional volumetric brain scans is to
reduce the anatomical variability between the images scanned from different individuals …

Image deformation methods in particle image velocimetry are becoming more and more
accepted by the scientific community but some aspects have not been thoroughly …

Causal exponentials play a fundamental role in classical system theory. Starting from those
elementary building blocks, we propose a complete and self-contained signal processing …

Time delay estimation (TDE) lies at the heart of signal processing algorithms in a broad
range of application areas, including communications, coherent imaging, speech …

The quantitative assessment of cardiac motion is a fundamental concept to evaluate
ventricular malfunction. We present a new optical-flow-based method for estimating heart …

Being able to acquire, visualize, and analyze 3D time series (4D data) from living embryos
makes it possible to understand complex dynamic movements at early stages of embryonic …
