چکیده

In this paper, an H.264/AVC-based multiple description video coding scheme is proposed. It utilizes the advanced video coding tools and features provided in H.264/ AVC to introduce redundancy into descriptions. Two independently decodable descriptions are generated, each consisting of two slice groups. One of them, called main slice group (MSG), is encoded normally as main information. The other one, called side slice group (SSG), is encoded with fewer bits as redundancy information by using larger quantization step sizes. Spatial and temporal correlations between neighboring macroblocks in video frames are exploited to achieve efficient redundancy coding. Experimental results show that the proposed MDC scheme is superior to previous slice group based multiple description coding (MDC) schemes in terms of the rate-distortion (R-D) performance. & 2008 Elsevier B.V.

Automatic Video Captioning via Multi-channel Sequential Encoding

In this paper, we propose a novel two-stage video captioning framework composed of 1) a multi-channel video encoder and 2) a sentence-generating language decoder. Both of the encoder and decoder are based on recurrent neural networks with long-short-term-memory cells. Our system can take videos of arbitrary lengths as input. Compared with the previous sequence-to-sequence video captioning frame...

Reconstruction Network for Video Captioning

In this paper, the problem of describing visual contents of a video sequence with natural language is addressed. Unlike previous video captioning work mainly exploiting the cues of video contents to make a language description, we propose a reconstruction network (RecNet) with a novel encoder-decoder-reconstructor architecture, which leverages both the forward (video to sentence) and backward (...

Algorithms for Power Consumption Reduction and Speed Enhancement in High-Performance Parallel Multipliers

This paper presents a new two-gate-delay implementation of the Booth encoder and partial product generator, which eliminates the unnecessary glitches associated with the Booth multiplier. In addition, a modified signed/unsigned (MSU) and modified sign-generate (MSG) algorithms, suitable especially for signed/unsigned multipliers, were developed in order to reduce the compression level needed in...

Multiple Description Coding for Video Using Motion Compensated Prediction

We propose multiple description (MD) video coders which use motion compensated predictions. Our MD video coders utilize MD transform coding and three separate prediction paths a t the encoder, to mimic the three possible scenarios at the decoder: both descriptions received or either of the single descriptions received. We provide three different algorithms to control the mismatch between the pr...
