    Shows how the Viterbi decoding algorithm (VDA) can be used for signal equalization and detection in a way that is quite different from the usual equalization approach of adjusting a received signal via filtering to "reverse" the distortion. With the VDA, the receiver "adjusts itself" so as to make good data estimates from a distorted sequence of waveforms. The main goal of this article has been to... View full abstract»

    Super-resolution (SR) restoration aims to solve the following problem: given a set of observed images, estimate an image at a higher resolution than is present in any of the individual images. Where the application of this technique differs in computer vision from other fields is in the variety and severity of the registration transformation between the images. In particular this transformation is... View full abstract»

    Described methods for simultaneously generating the super-resolved depth map and the image from LR observations. Structural information is embedded within the observations and, through the two formulations of DFD and SFS problems, we were able to generate the super-resolved images and the structures. The first method described here avoids correspondence and warping problems inherent in current SR ... View full abstract»

    A new approach toward increasing spatial resolution is required to overcome the limitations of the sensors and optics manufacturing technology. One promising approach is to use signal processing techniques to obtain an high-resolution (HR) image (or sequence) from observed multiple low-resolution (LR) images. Such a resolution enhancement approach has been one of the most active research areas, an... View full abstract»

    The attainment of super resolution (SR) from a sequence of degraded undersampled images could be viewed as reconstruction of the high-resolution (HR) image from a finite set of its projections on a sampling lattice. This can then be formulated as an optimization problem whose solution is obtained by minimizing a cost function. The approaches adopted and their analysis to solve the formulated optim...

    Surveys the field of super resolution (SR) processing for compressed video. The introduction of motion vectors, compression noise, and additional redundancies within the image sequence makes this problem fertile ground for novel processing methods. In conducting this survey, though, we develop and present all techniques within the Bayesian framework. This adds consistency to the presentation and f... View full abstract»

    Explored the basic theory of recursive digital oscillators with a bent towards the practical, and from there looked at some common oscillators. Then the article added some mechanisms for controlling their amplitude and adjusting their frequency. A brief example of how these oscillators and their control mechanisms may be used to make FSK modulators is given. View full abstract»

    Dirty-paper coding makes an analogy to the problem of writing on dirty paper, where the reader cannot nominally distinguish dirt from ink. There are many scenarios where this result may be applied. In the field of information hiding (or watermarking), theoretical bounds as well as practical watermarking schemes have been found. Another important application of dirty-paper coding is for a multiuser... View full abstract»
