The purpose of this study was to investigate the efficacy of in-home telerehabilitation as an alternative to conventional rehabilitation services following knee arthroplasty. Five community-living elders who had knee arthroplasty were recruited prior to discharge from an acute care hospital. A pre/post-test design without a control group was used for this pilot study. Telerehabilitation session...

SUMMARY The H.264/AVC standard provides several new error-resilient features to enable the reliable transmission of compressed video signals over lossy packet networks. Flexible Macroblock Ordering (FMO) is one of the most interesting resilient features within the H.264/AVC standard. Unlike former standards, in which slices were constructed out of consecutive raster scan macroblocks, FMO sugges...

Video compression has been investigated by means of analysis-synthesis, and more particularly by means of inpainting. The first part of our approach has been to develop the inpainting of DCT coefficients in an image. This has shown good results for image compression without overpassing todays compression standards like JPEG. We then looked at integrating the same approach in a video coder, and ...

Video streaming over mobile ad-hoc networks is becoming a highly important application for reliably delivering the content between the user and the content storage node. The key challenge is, hence, to address the impact of the user mobility on the quality of the delivered video. Accordingly, the pioneering concept of network coding (NC) emerges as a promising approach for improving the video t...

The H.264/AVC standard gives a few new slip flexible peculiarities to empower the dependable transmission of compacted feature motions over lossy bundle systems. Adaptable Macroblock Ordering (FMO) is a standout amongst the most fascinating strong peculiarities inside the H.264/AVC standard. Dissimilar to previous principles, in which cuts were built out of sequential raster check macroblocks, ...

This paper presents an adaptive motion estimator that can be dynamically reconfigured by the best algorithm depending on the variation of the video nature during the lifetime of an application under running. The 4 Step Search (4SS) and the Gradient Search (GS) algorithms are integrated in the estimator in order to be used in the case of rapid and slow video sequences respectively. The Full Sear...

Source classification has been widely studied in conventional coding of image and video signals. This paper explores the idea of exploiting so-called classification gain in Wyner-Ziv (WZ) video coding. We first provide theoretical analysis of how source classification can lead to improved Rate-Distortion tradeoff in WZ coding and quantify the classification gain by the ratio of weighted arithme...
