    Robust reconstruction of Wyner-Ziv frame for no-feedback distributed video coding by Hao QIN, Xue-lu PENG, Bin SONG, Hai-hua LIU

    Published 2012-01-01
    “…In no-feedback distributed video coding,a robust reconstruction algorithm for Wyner-Ziv frame was proposed.To avoid the video quality degradation caused by the bit plane decoding errors,DC coefficients and AC coefficients were reconstructed with different methods.In particular,for each failure decoded quantized DC coefficient,with the help of the correlation information from the encoder,the algorithm was able to adaptively adjust the contribution of the quantized side information and the decoded quantized DC coefficient to the reconstruction.Simulation results show that compared with the MMSE (minimum mean square error) algorithm,the proposed method can increase the average PSNR (peak signal-to-noise ratio) of reconstructed video greatly,and also yield significant improvement of the subjective video quality.…”

    Video matching method based on "bag of words" by LI Yuan-ning1, LIU Ting1, JIANG Shu-qiang1, HUANG Qing-ming1

    Published 2007-01-01
    “…A "bag of words" was presented based method for video representation and matching.First,all local features of all video frames were quantized into a dictionary of visual words.Then each sub-shot of the video was represented by a set of visual words.Finally,a revered index of visual words was created to speed the matching process of video clips.This method not only takes local appearance and spatial information into account,but also compresses the representation of video content.Highly competitive experimental results show that our proposed method is more effective and efficient than former methods for video matching in large video dataset.…”

    Robust image hashing method from global perception features of human visual cortex by SUN Rui1, YAN Xiao-xing2, GAO Jun1

    Published 2011-01-01
    “…Firstly,the image was filtered low-passly and re-scaled to fixed size.Then the image was divided into key-dependent overlapping blocks.According to the hierarchical structure of HVS primary visual cortex,directional contour responses were extracted through layer-by-layer processing of visual pathway,and global perception features could be obtained by associating with the surface color of each blocks.These features included image direction and color information.The relation of adjacent entries was invariant to ordinary image processing.It could be used to quantize and permute these feature to get the binary image hash.Test results indicate that the proposed method is robust against con-tent-preserving modifications such as JPEG compression and filtering,at the same time,is capable of localizing image malicious tampering.Hashes of different images have very low collision probability.…”
