In this paper, we describe the Beatsens Team solution of Emotion in Music task in MediaEval benchmarking campaign 2014. We extracted and designed several sets of features and used continuous conditional random field(CCRF) for dynamic emotion characterization task. The best runs for Pearson correlation are 0.23 ± 0.56 and 0.12 ± 0.55 of valence and arousal… (More)
In this paper, we describe the PKU-AIPL Team solution of Emotion in Music task in MediaEval benchmarking campaign 2015. We extracted and designed several sets of features and used continuous conditional random field(CCRF) for dynamic emotion characterization task.
Previous researches have shown some approaches on hardware phase detection. In this work, we propose a new framework based on Xilinx Virtex-6 platform for the implementation of task-optimized coarse-grained reconfiguration that can be reconfigured to adapt to the applications' behavior. We use MicroBlaze as a general-purpose processor and a ρ-VEX VLIW… (More)
We participate in all two types of known-item search task of TRECVID 2012: automatic search and interactive search. This paper presents our approaches and results. We adopt three kinds of text information, which are XML documents, ASR and OCR. And we index and search the three kinds of pre-processed text individually with Lucene. In addition, the results… (More)
In this paper, we suggest an adaptive watermarking method to improve both transparence and robustness of quantization index modulation (QIM) scheme. Instead of a fixed quantization step-size, we apply a step-size adapted to image content in each 8×8 block to make a balance of robust extraction and transparent embedment. The modified step-size is determined… (More)
