Error resilient coding and error concealment in scalable video coding
Pages 781–795

Scalable video coding (SVC), which is the scalable extension of the H.264/AVC standard, was developed by the Joint Video Team (JVT) of ISO/IEC MPEG (Moving Picture Experts Group) and ITU-T VCEG (Video Coding Experts Group). SVC is designed to provide ...

Optimized video multicasting over wireless ad hoc networks using distributed algorithm

Recently there has been a compelling need to support real-time video multicast from a single source to multiple receivers in wireless ad hoc networks. The existing work uses tree-based schemes to perform video multicast. The optimization of those ...

Hierarchical space-time model enabling efficient search for human actions

We propose a five-layer hierarchical space-time model (HSTM) for representing and searching human actions in videos. From a features point of view, both invariance and selectivity are desirable characteristics, which seem to contradict each other. To ...

An object-based approach to image/video-based synthesis and processing for 3-D and multiview televisions
Pages 821–831

This paper proposes an object-based approach to a class of dynamic image-based representations called "plenoptic videos," where the plenoptic video sequences are segmented into image-based rendering (IBR) objects each with its image sequence, depth map, ...

Places clustering of full-length film key-framesusing latent aspect modeling over SIFT matches

An improved unsupervised classification method to extract and link places features and cluster recurrent physical locations (key-places) within a movie is presented. Our approach finds links between key frames of a common key-place based on the use of a ...

Weighted fuzzy reasoning scheme for interlaced to progressive conversion

Video deinterlacing can be realized usiug time-space interpolation filters. To improve video deinterlacing quality with respect to missing pixels on moving diagonal lines, we developed a fuzzy concept that utilizes deinterlacing methods. The proposed ...

The multiple-camera 3-D production studio

Multiple-camera systems are currently widely used in research and development as a means of capturing and synthesizing realistic 3-D video content. Studio systems for 3-D production of human performance are reviewed from the literature, and the ...

Temporal segmentation of 3-D video by histogram-based feature vectors

Three-dimensional (3-D) video, which is a sequence of time-varying mesh models generated in a multi-camera studio is attracting increased attention, because it can record and reproduce the 3-D information of real-world objects with high accuracy. As one ...

Pre- and post-shift filtering for blocking removing in downsizing transcoding

When high-quality video is delivered via a bandwidth-limited network, one solution is to reduce the spatial resolution of the bitstream before transmission. Downsizing transcoding is adopted as an efficient tool to reduce the spatial resolution of the ...

Fine-granular motion matching for inter-view motion skip mode in multiview video coding

As motion of neighboring views is highly correlated in multiview video systems, the inter-view motion skip mode has been proposed to improve the efficiency of multiview video coding (MVC) by reusing the motion information of neighboring views. To fully ...

A novel prediction-based directional asymmetric search algorithm for fast block-matching motion estimation

This paper proposes a very fast block-matching motion estimation algorithm for video compression. This method uses a new concept involving a very compact center-biased characteristic in developing directional asymmetric search patterns, which we refer ...

A novel illumination-balance technique for improving the quality of degraded text-photo images

Content digitization transforms a source into its digital form through digital cameras or scanners. This transformation often leads to the irregular distribution of image illumination, which may distort the quality of digital images. Engineers have ...

Reversible data hiding based on histogram modification of pixel differences

In this letter, we present a reversible data hiding scheme based on histogram modification. We exploit a binary tree structure to solve the problem of communicating pairs of peak points. Distribution of pixel differences is used to achieve large hiding ...

research-article
Carried object detection using ratio histogram and its application to suspicious event analysis

This letter proposes a novel method to detect carried objects from videos and applies it for analysis of suspicious events. First of all, we propose a novel kernel-based tracking method for tracking each foreground object and further obtaining its ...
