The generation of high-resolution mosaics from multiple images is presented. The estimation of the high-resolution signal utilizes a motion-compensated filtering approach for video frames that are affected by spatial aliasing. For that, global motion models and the corresponding estimation algorithms are employed to provide a very accurate and continuous description of sub-pixel motion for the ...

Co-registered optical coherence tomography (OCT) and video microscopy of the rat somatosensory cortex were acquired simultaneously through a thinned skull during forepaw electrical stimulation. Fractional signal change measured by OCT revealed a functional signal time course corresponding to the hemodynamic signal measurement made with video microscopy. OCT can provide high-resolution, cross-se...

This pape? presents a novel approach to dynamic transmission bandwidth allocation for transport of real-time variable-bit-rate video in ATM networks. Describe video traffic in the frequency domain: the low frequency signal captures the slow time-variation of consecutive scene changes; the high frequency signal exhibits the feature of strong frame autocorrelation. Our study indicates that the vi...

The UPC system works by extracting monomodal signal segments (face tracks, speech segments) that overlap with the person names overlaid in the video signal. These segments are assigned directly with the name of the person and used as a reference to compare against the non-overlapping (unassigned) signal segments. This process is performed independently both on the speech and video signals. A si...

In this paper we introduce wavelet video processing of proximity sensor signals. Proximity sensing is required for a wide range of military and commercial applications, including weapon fuzing, robotics, and automotive collision avoidance. While our proposed method temporarily increases signal dimension, it eventually performs data compression through the extraction of salient signal features. ...

Liquid Crystal Displays (LCDs) have improved so dramatically over the past years, that they have rapidly overtaken the TV market. At the moment, one major aspect where LCDs are still inferior to the traditional Cathode Ray Tube (CRT), is the resolution of moving images, i.e. dynamic resolution. In this paper, we review some of the proposed methods to improve this aspect, from a video signal pro...

As communications get digital there is an increased use of image and video processing in embedded multimedia applications. Digital signal processors (DSPs) provide excellent computing platforms for these applications not only due to their superior signal processing performance compared to other processor architectures, but also because of the high levels of integration and very low-power consum...

Coherent and non-coherent radar detection of moving targets is analyzed and expressions relating the post-video-detection moving target signal-tonoise ratio to the pre-video-detection moving target signal-to-noise and clutter-to-noise ratios are obtained for non-coherent detection. The effect of processing this resulting real (non-coherent) signal with an FFT processor is then analyzed and comp...
