Concurrent Decoding Method for Multi-channel Motion Video Signals.

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...

Video coding with superimposed motion compensated signals

A robust motion detection and estimation filter for video signals

The problem of detecting areas of motion in video sequences and estimating parameters such as speed, direction and dynamics is addressed in many applications of image processing such as video surveillance, object tracking, image stream compression or autonomous navigation systems. Real world computer vision highly depends on reliable, robust systems for recognition of motion cues to make accura...

Finger Motion Decoding Using EMG Signals Corresponding Various Arm Postures

We provide a novel method to infer finger flexing motions using a four-channel surface electromyogram (EMG). Surface EMG signals can be recorded from the human body non-invasively and easily. Surface EMG signals in this study were obtained from four channel electrodes placed around the forearm. The motions consist of the flexion of five single fingers (thumb, index finger, middle finger, ring f...

Architecture for Multi-Client Multi-Channel Compressed Video Streaming

In this paper we describe an architecture for a multi-client, multi-channel video streaming server targeted at the security market. For each connected client, the best selection of available compressed video streams per channel is made, optimizing the perceived quality of the video channels requested by the client. We propose techniques to scale the bitrate per video stream and introduce a sche...
