Spline-based signal reconstruction algorithm from multiple level crossing samples
Commonly used analog-to-digital converters sample signals uniformly. The sampling rate is determined by maximal frequency in signal spectrum. In the general case the spectral content of the majority of signals encountered in our everyday life changes over time. The main idea behind level-crossing sampling is to take advantage of the characteristics of the input signal in order to minimize activ...
متن کاملProcessing of Non-Stationary Signal Using Level-Crossing Sampling
The spectral characteristics of multimedia signals typically vary with time. Preferably, the sampling density of them would comply with instantaneous bandwidth of signal. The paper discusses the level-crossing sampling principle, which provides such capability for analog-to-digital conversion. As the captured samples are spaced non-uniformly, the appropriate digital signal processing is require...
متن کامل3D-spline reconstruction using shape from shading: Spline from shading
In this work, we describe an original method of solving the shape from shading (SFS) problem, which relies on the marriage of two simple ideas. On the one hand, we propose to modelize the scene by a parametric surface, namely a 3D-spline. The key advantage is that boundary conditions are no longer required to render the problem well-posed. On the other hand, we introduce the concept of ‘‘useful...
متن کاملReconstruction from Non-uniform Samples
Exact reconstruction of a band-limited signal from its non-uniform samples involves the use of Lagrange interpolation, which is impractical to implement as it is computationally difficult. This thesis develops approximate reconstruction methods based on time-warping to obtain reconstruction of band-limited signals from non-uniform samples. A review of non-uniform sampling theorems is presented ...
متن کاملMultiband signal reconstruction from finite samples
The minimum mean-squared error (MMSE) estimator has been used to reconstruct a band-limited signal from its finite samples in a bounded interval and shown to have many nice properties. In this research, we consider a special class of bandlimited 1-D and 2-D signals which have a multiband structure in the frequency domain, and propose a new reconstruction algorithm to exploit the multiband featu...
