background: end stage renal disease negatively affects the patients’ quality of life. there are different educational methods to help these patients. this study was performed to compare the effectiveness of self-care education in two methods, face to face and video educational, on the quality of life in patients under treatment by hemodialysis in education-medical centers in urmia. methods: in ...

We present a user-basedmethod that detects regions of interest within a video in order to provide video skims and video summaries. Previous research in video retrieval has focused on content-based techniques, such as pattern recognition algorithms that attempt to understand the low-level features of a video. We are proposing a pulse modeling method, which makes sense of a web video by analyzing...

The explosive growth of digital video content from commodity devices and on the Internet has precipitated a renewed interest in video processing technology, which broadly encompasses the compression, enhancement, analysis, and synthesis of digital video. Video processing is computationally intensive and often has accompanying real-time or super-real-time requirements. For example, surveillance ...

Multiple description coding has been shown to provide improved error resiliency for video streaming over error-prone channels. In a typical multiple description codec, the decoder simply reproduces the signal using the received description(s). The optimal reconstruction is obtained from the available description in the sense that the mean squared error is minimized. However, this reconstruction...

Automatic identification of TV programs within TV streams is an important task for archive exploitation. This paper proposes a new spatial-temporal approach to identify programs in TV streams in two main steps: First, a reference catalogue for video grammars of visual jingles is constructed. We exploit visual grammars characterizing instances of the same program type in order to identify the va...

We model the decoded picture quality at the output of a Systematic Lossy Error Protection (SLEP) scheme for error-resilient transmission of H.264/AVC compressed video signals. In this scheme, a video signal transmitted without channel coding constitutes the systematic portion of the transmission. Errorresilience is provided by transmitting a supplementary bit stream generated by Wyner-Ziv encod...

Motion information has been widely exploited for group activity recognition in sports video. However, order to model and extract the various motion between adjacent frames, existing algorithms only use coarse video-level labels as supervision cues. This may lead ambiguity of extracted features omission changing rules patterns that are also important video recognition. In this paper, a latent la...

In this paper we investigate robust watermarking integrated with H.264/SVC video coding and address coarse-grain quality and spatial resolution scalability features according to Annex G of the H.264 standard. We show that watermark embedding in the base layer of the video is insufficient to protect the decoded video content when enhancements layers are employed. The problem is mitigated by a pr...

The available channel bandwidth may vary due to many factors including network traffic congestion. Therefore, a video server should be able to decide how to reduce the transmission rate so as to maximize the signal quality at the receiver. The video encoder can scale the spatial resolution, temporal resolution or SNR to decrease the rate. In this paper, we study which option or which particular...

Video watermarking is well known as the process of embedding copy right information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video . In this study, an effective, robust DCT transform using MATLAB. In the proposed method, first the video frames are extracted from the host video. Then, each frame gets water...
